I guess it's one of those who don't read and just spam their art to EVERY group they manage to get in, no matter how stupidly dumb it is. I mean, if it has a meme from DOTA 2 in it, there's nothing to say, but this is just OCs from what I can tell.
Am I? I'm just stating facts. Most of the time, such things happen because an artist just checks all groups he's in to promote his art even if it isn't related. If you look carefully in the groups he picked, you'll see it went into OTHER wrong groups at the time I posted my first comment, which is why I stated that. Plus, would you like it if someone added really unrelated art into your fav group? You'll be questioning the exact same. More so if the art is of risqué materials, which thankfully, isn't the case with this.
