the most recent example i can find is that dirkdave pic, which is redlament's art. in the comments of the pic a couple people told you it was redlament's art, but i still don't see you changing/editing the post. It's been several months since the pic got posted, so i could see how you might forget but give artists credit. I mean, if you really want to find the artist do a reverse image search. there's no reason to leave it uncredited
I'll be honest I didn't see those comments until last week, but I fixed it ^~^ sorry for the inconvenience
