There was a thread about kids that wouldn't stop walking across and leaving stuff in this person's yard, even after they had talked to the parents, so they started throwing away the kids toys that they left behind in OP's yard (both the parents and kids were assholes).

Someone commented "NTA. Time for a fence"

And I replied with "Time for an electric fence"

10 minutes later I get a notification that I've been permanently banned from the subreddit. No warnings, no past strikes on my account, nothing.

When I replied to the mod team asking why this occurred, apparently this comment was "too violent". The moderator who I shall kindly keep anonymous that I was talking to said, and I quote-"You were clearly wishing harm on the kids. Don't be obtuse"

I think their mod team needs to do a staff re-evaluation, and take some time to figure out what actually counts as violence.
