On top of that. a privately-owned dating website/app has the right to decide you are too unattractive to participate, and therefore reject you. When the ratio of fatties to fit humans gets too high, members get annoyed and leave in disgust because they aren't pigfuckers and don't want to keep fielding PMs from obeasts. Gay men have always been notoriously exacting when it comes to standards of attractiveness, and "no fats" is common in gay men's personals ads (and so is the whining about it).  On top of that, gay men tend to be far more promiscuous than straights, or lesbian women (not judging; just stating a fact), so they are much more likely to be heavy users of a hookup website or app. If you want them to pay for features, you've got to make it worth their while, and thus "curating"--weeding out the fats, uggos, and decrepit olds--happens.
