What the posters above said:
Pictures with fish.
Pictures with kids who are not yours. I really hope you asked for their parents'consent.
Topless pictures, or worse - underwear pics. Ugh.
Mirror selfies - come on now, you can do better than this. Very low effort.
Multiple gym photos - ....
Pulling silly faces, sticking the tongue out - so unattractive in adult men.
Low quality selfies that looks like they were taken with a potato. Maybe they were.
Now onto description:
Passive aggressive comments ("if you don't talk, I WILL UNMATCH!!", "If you don't look like your pictures, you're buying drinks until you do!" - how about the other way round?).
The age "mistake". Especially bad if there's no mention in the profile and you find out later, to which they say "Oh I was sure I mentioned it". Yeah, no. And later "I feel and look younger than my age". But you're still old.
Instagram handle.
Spelling mistakes (your/you're etc.) - little things that matter.
Own house, own car, own teeth - clap clap, just sounds like you're boring tbf.
