Yup.. although looking back it was TumblrinAction. but nonetheless... it is absolutely ridiculous. That was the message I had received when I posted there.

"You have been permanently banned from participating in r/offmychest. You can still view and subscribe to r/offmychest, but you won't be able to post or comment.

Note from the moderators:

You have been automatically banned for participating in TumblrInAction, which has systematically harmed this community.

TiA's creator admits TiA is a hate group. A TiA mod resigned because of that. TiA is known to the Internet as one of Reddit's main harassment sources. A TiA member was arrested for "terrorist threats" after boasting about it, which the community supported and asked how to join in on.

Regardless of context, contributions you provide to the hatereddit is a material form of support. The only thing we are willing to discuss, now that you are aware, is if you will no longer support abuse and harassment by no longer participating in hatereddits. We will ignore any other response."
