I don't cause it always just makes people mad or sad cause they can't see it. If people say it's bad on one of my old pics i can call them lazy for not even looking at my new pictures. I delete my bad art or art I don't care for only when I really have to. I think I've only ever deleted my bad bases.
If people are stealing my art, or not paying for them, I WILL store them until they do or leave. I don't really CARE if they get mad/sad the image is deleted if they didn't do their part of the deal.
You didn't read my comment - storing goes to people who try to scam me out for free art (this has happened recently). As long as you PAID your end for the art I won't store it. If you don't do your end of the trade or payment I will store the art I did until your end is paid. {Hence storing rather than deleting}
I will go after the people who stole it, but I will leave it up for proof for the DA staff to see.
