If a submission has comments disabled, don't send comments about the piece to the artist via the note system. It's fucking rude..
If they wanted to have comments about the piece, then they would have left the comments enabled.

I've gotten no less than three messages about the last one. I am not going to reply to any of them, I am just going to delete them.
Do not say "finally someone who understands" or "I know how you feel" if you are not within my circle. I have only told about six people the entire story. Some of the friends that I talk to every single day and treat like family don't know the full story. Acting like you know how someone feels about a situation you have not been told about in its entirety is fucking rude.

I don't mind the messages like "if you need to talk, my inbox is open" [i sort of delete those anyway, but the thought is noted and appreciated] but when people try to kiss my ass and act like they know what's going on, that is what pisses me off and that's the quickest route to getting on my shitlist.

Do not send me "Im sorry" messages about this, I have no interest in your apologies. Just don't do it again.
