i think the whole thing is about the payout. If there was not payouts then nobody would care. For example i think a profile that always uploads memes (that probably are stolen) or just a single photo per day isn't considered quality. About the photography one i am talking about photos of a shoe, of a bottle in general ''useless'' photo that show that the person just wanted to upload something. Meanwhile a single photography can have deep meanings ( μια εικονα χιλιες λεξεις)

Also it's not the same when someone makes general posts or in a specific genre and once in a while he posts a gif or meme. He doesn't lose his quality i think.

At the end of the day it's as you said what please us and if i may add we are the ones who casts our votes too!
