When you see an unusual amount of comments on one of your works and think "wow I didn´t notice so many people cared to say somthing about it!" then you check it and it is a chat or rp of two people which has nothing to do with your shit.
Lmao I did this to my own art and it has 102 or something comments just because me and my penpal were messing around RP'ing on it. XD Before that I did a sort of battle RP with this guy, it'd happen when I made a comment on how Slender man was disappointed and then we started doing a little chat. XD Hey if the artist themselves is RP'ing with you then it ain't no big deal. But for commenters to do it by themselves I guess that'd be disappointing to look at. I don't really see the problem tho unless the RP is fetish or something messed up like that. But your art, your rules. XD and they outta respect it once their told so.
Guilty, guilty as anything, I have a bad habit of RPing, but however I only do it at the right place at the right time, I wouldn't go to some random picture and get into a full blown RP, instead I take it to note, when I first started on the internet, when I was 25, I used to, but then I thought that was rude of me and unfair on the artist, even though I have been very lucky that the artist I know here have been very nice about it, but still there is a time and place for that stuff really, so it is a matter of respect the artist
