I hate when friends cross post art all over the place, and the same people will see it no matter where it's posted. I mean...I do this, but my fb friends and family are separated from my DA/tumblr. Also, I had this friend for a while irl that would go to the little suncoast/fye anime days, and then self promote her DA there. Like she got like....her 2 or 5k kiriban or w/e and the person who caught it, she knew irl, so she like....shot a video on front of the store, her awarding her friend with a piece of paper that said "1 free commission." http://shard-chan.deviantart.com/ (HAVE FUN LOOKING AT THAT BTW) She got kind of extremely butthurt when she found my DA, and I had like, 20k views at the time. Speaking of "1 free commission", that's another thing i kind of hate. The misuse of words on DA. Commission, mostly.
A few years ago when I was still actively making comics (one shots or notebook series), stupid weeaboo highschool friends would often ask if they should read from right to left.
faggots who fave 344565 pictures per day, and then complain if they get too many "thank you" messages. a while ago, i used to watch a person who at a time started favewhoring and watchwhoring, and she put a stamp that stated something like "don't thank me for comments/favs/watches. take a look at my gallery instead". basically, she was admitting that she was faving so much and watching everyone only to get attention. btw favewhores and watchwhores piss me off in general, whether they complain or not.
