>>10397507pepe is a neutral meme in general (with the exception of some overly-sensitive crybabies who think it is a hate symbol due to occasional use of it in that way on /pol/) so you see it a lot on boards that don’t have a lot of great visuals otherwise. /sci/ by nature of the subject doesn’t have the most flashy pictures (contrast with e.g. the photography board or /v/ or /out/) so pepe is a decent default image. the other default images for threads with no good topical image are usually anime, and honestly i’d rather see pepe than anime crap
