and to my knowledge those are, research, gore, and screamers
those all depend
if someone was spamming them, yes, permanent
but if someone just posted like, one or two images, not realizing that they were bad enough to get banned, or linking to a screamer or rickroll or something, I guess forgetting it was against the rules, nah
foxscotch posted research once and it was a 1 month ban
2nd time he did it it was perma
actually it was a week, and it was my fourth ban. badspot really isn't that harsh when you aren't actively trying to hurt anything
