I noticed a number of subreddits came back a while ago, but in decidedly passive-aggressive ways. One is read-only and prevents anyone from posting any topic or reply. Another got rid of all its rules and permanently marked every post as NSFW. It's clear they're just trying to exploit loopholes to avoid getting banned while still putting up resistance, but it'll be interesting to see how Reddit deals with them once the admins get sick of their shit.
