So having been using the app for 3-4 years (M30) dating girls, the types I met is

1.) The "20 year olds"; I assume they get infinite attention, so their profile is often only look-down selfies with no profile (or really bitchy/"I'm a queen, entertain me" profile). Zero personalities if you ever end up meeting one, dry texting unmatched by even chat-bots. I struggle to see how anyone except thirsty sex maniacs can stand them. People above 20 y.o can have this attitude but it seems to die out by 25-30.

2.) The "all basic 101s checked out" girls; Have a profile that explain themselves and what they are looking for, they can hold an decent conversation over text, Pictures show their face & hobbies without filter. Usually decent people, no red flags & even if a date does not lead to anything, you have a good time.

3.) The "Hidden gems"; No profile, maybe one picture. Really suspicious & looks like low effort but sometimes it's just a new profile; they can hold a conversation and you might be in for a pleasant surprise (this was my ex). Can also be the most blandest of people.

4.) The "Damaged"; Usually you'll notice something is off while you're texting. If you end up setting up an date, high likelihood that it will be quite a unpleasant experience, even though it might lead to surprise ONS or similar. They either carry around a lot of negativity or coping mechanism that will be a burden to you. Most often closer to the character disorder spectrum rather than neurotic.

5.) Fear driven Frida, Shallow Sharon, The needs driven "Selfish Stanley"
