It's submitted into eight groups on top of the artist already being reputable and having built their gallery on this very subject. It might not be the most visually appealing but the subject is widely liked and the photo quality is good which is enough for people on DA. If Tom Prestons sad comic series can get front page, this it's no surprise good quality wolf photos do.
One thing is for sure though, you sure as hell aren't gonna make front page with screencaps.
Nah his caps aren't even funny. I used to do the same except I wasn't as laughable as him. It's true though, he's just bitching but he has no work so why even both whine about who gets on the front page if he isn't putting any effort into art what so ever. lol He's just mad.
I wouldn't worry. You not only have more fans but you devote you time to worthy things. He'll only get banned if he spams you or if he continues to comment on your stuff using an alternate account since you blocked him.
