I know some of you will find this as a popular action because it was generally spammy but I didn't personally see a problem with it because it's drawing related (even though it's digital).
I never did like all those high-rule subs on other sites because it's stupid nonsense designed to control the conversation. The artist attribution rule, however, is to straight up prevent theft whenever possible. I want to be able to share my artwork but people reposting and stealing prevents me.
Sharing is one thing, posting ONLY your own stuff is spamming.
You tried to get them to act right, they didn't listen. Justified.
