i only use okcupid. i think part of the what helps is that my profile is very long. i honed it to perfection over many a drunken night
since i only reply to messages from guys who clearly read (and liked) my stupid long profile, i have already cut out a lot of the idiots.
idk your age range, but i also tend to only meet guys in their 20s, so there isnt much room for fake pics there. i have found when i meet older guys in their 30s, they ALWAYS look older, facially, than their pics showed. personally im just not into guys that are a lot older than me though.
i dont think i have any tricks, i think its just my personality. it doesnt attract the kind of guy who is so insecure he would do fakey stuff with his pics
i will also say that i recognise guys ive seen from okcupid ALLLLLLLLLLLLLLLLLLLLLL the time. i think that was just last weekend, or the weekend before, i went out with an lhcf lady and before she got there i recognised a guy whose okcupid profile i had stalked before
damn he was cute
i will say if i do come across a guy whose pics are suspect, i just reverse google image search them and find their other social media
thats gotten me out of meeting a few fluffy ones
