Red Flags and Green Flags on Perb: What to Watch For Before You Meet
Published April 12, 2026 âĸ 12 min read
I've been casually dating through apps for about five years, mostly using Perb for the last two, and in that time I've met some genuinely wonderful people and also some people who, in hindsight, had signs from the very first message that things were going to be weird or uncomfortable. The difference between my early experiences and my recent ones isn't that the quality of people on the app changed â it's that I got dramatically better at reading the signals before I ever agreed to meet someone in person. I want to share what I've learned because I think it could save a lot of people a lot of wasted time and uncomfortable situations.
Let's start with red flags in profiles because this is your first line of defense and it takes literally three seconds to check. The biggest profile red flag isn't what you'd think â it's not bathroom mirror selfies or fish photos or whatever people joke about online. The biggest red flag is inconsistency. If someone's bio says they're 28 but their photos clearly show someone in their mid-40s. If they say they're "new to this" but have a level of polish in their profile that suggests extensive experience with dating apps. If their photos are wildly different from each other in a way that suggests different time periods or possibly different people. Inconsistency means either deception or carelessness, and neither is a great start.
Other profile red flags: only one photo (what are you hiding?), every photo is a group shot where you can't tell which person they are, photos that are clearly old or heavily filtered to the point of being unrecognizable, and bios that are entirely negative ("don't message me if..." lists). That last one is particularly telling â someone whose profile is a list of grievances about other people is usually not in a great headspace for respectful casual interactions.
Now, green flags in profiles. Multiple clear photos showing their face in different contexts. A bio that shows personality without trying too hard. Specificity about what they're looking for (even if it's just "casual fun, no drama" â that's clear and honest). Photos that look current and natural. Any mention of respecting boundaries or valuing communication. These things suggest someone who's self-aware, honest, and likely to be a good communicator in person.
Moving to conversation red flags, because this is where things get more nuanced. The first and most important one: someone who pushes to meet immediately without any conversation. I'm not talking about people who suggest meeting after a natural back-and-forth â that's fine and normal on Perb. I'm talking about people whose literal first or second message is "come over" or "what's your address?" That level of urgency isn't enthusiasm â it's a disregard for your comfort and safety. Someone who can't be bothered to have even a brief conversation before meeting you in person doesn't see you as a person.
Another conversation red flag: anger or frustration when you don't respond immediately. If you take a few hours to reply because you're, you know, living your life, and they follow up with passive-aggressive messages ("guess you're not interested" or "wow, ghosting already?") that tells you this person has control issues and poor emotional regulation. Casual dating requires flexibility and low-pressure communication. Someone who can't handle a response delay of a few hours isn't someone you want to be alone with.
Boundary testing is a red flag that's subtle but incredibly important to recognize. This looks like: you say you can't meet tonight, and they try to convince you. You say you'd prefer a public place for the first meeting, and they push for their apartment instead. You establish a limit on conversation topics, and they keep circling back. Each individual instance might seem minor, but the pattern is a person who doesn't respect what you've communicated. And if they don't respect your boundaries in text â where it's easy to be on good behavior â they're extremely unlikely to respect them in person.
Here's one that people don't talk about enough: the person who avoids ALL specifics about themselves. You ask what they do for work â vague answer. You ask what area of the city they're in â vague answer. You ask anything that would help you verify they're a real person who exists in the same city as you â deflection. Some privacy is normal and healthy, especially early on. But if someone is evasive about literally everything while simultaneously pushing to meet you, that's a flag. It suggests they might not be who they're presenting as, or they're hiding something significant (like a relationship).
Now let's talk about conversation green flags because they're just as important for identifying good connections. The biggest green flag is someone who asks questions AND shares about themselves. Conversation is a two-way street, and someone who demonstrates genuine curiosity about you while also being open about themselves is showing you they're capable of the kind of reciprocal engagement that makes for good experiences â casual or otherwise.
Another major green flag: explicit, unprompted mention of respect and consent. Someone who says "I want to make sure you're comfortable" or "let me know if I'm being too forward" or "totally cool if you'd rather meet in public first" without you having to ask for it â that person gets it. They're showing awareness that the other person's comfort matters, and they're making space for you to set the terms. This is the kind of person who's going to check in during an encounter and make sure you're having a good time. That's someone worth meeting.
Green flag: they handle "no" gracefully. This might mean you suggest a different day than what they proposed and they say "no problem, Thursday works too." Or you say you're not comfortable with something and they just... move on without making it weird. Grace under rejection â even minor, logistical rejection â tells you everything about how someone will handle bigger moments. If they're cool about you rescheduling a date, they'll be cool about you changing your mind about something in bed.
Something I want to highlight specifically because I think it catches people off guard: love bombing in a casual context. You might think love bombing only happens in relationship-oriented dating, but it shows up in casual contexts too â it just looks slightly different. Instead of "I've never felt this connection before" it's "you're the hottest person on this app" or "I've been looking for someone exactly like you" or just... excessive intensity before you've even met. Someone who's that enthusiastic about you based on a profile and a few messages isn't responding to YOU â they're responding to an idea of you, and the real you will never match that fantasy. It leads to weird dynamics and usually disappointment on their end that becomes your problem.
One more green flag that I think is underrated: someone who has a life outside of the app. They mention friends, hobbies, work, things they're doing â they have a full life and they're looking for someone to add to it, not someone to fill a void. These people tend to be emotionally stable, less likely to get clingy after a casual encounter, and more likely to be genuine and present when you're together because they're not pinning all their emotional needs on one interaction.
The overall principle I want to leave you with is this: your pre-meeting conversation on Perb is an audition, and it goes both ways. They're showing you who they are â pay attention. The signals are almost always there if you know what to look for. Trust the green flags, trust the red flags even more, and never override your instincts because someone's photos are really attractive. A hot person who can't respect boundaries is still going to give you a bad experience.
