Why/when RL was banned? It's probably from this thread a couple days ago which had mods on multiple occasions admonishing RL, who completely ignored them and insulted them in return. Specifically, this comment line comes to mind for why he was finally banned. Follow the deleted comment thread to see; there's also input from the mods. Here's the deleted post, with the link edited out for privacy.

Basically, someone told RL to "grow up mate." In RL's lust to make a swipe back, he checked their posting history and cited a suicide thread as ammunition to discredit him. RL later claimed he didn't actually read the suicide thread, so I guess that means he somehow stumbled on the perfect thread to undermine the other person purely by "coincidence." In the same post, RL offered to talk with the other person about their suicidal thoughts, "despite the shit he'd talked about RL" (apparently grow up mate counts as shit talking), as if RL was the one showing generous mercy to someone who had committed the greater offense.

The mods have been asking RL repeatedly to cool it on the subreddit and examples like above are why. Every time they told him to stop, he just talked shit about them in response or elsewhere, directly on the subreddit. He's had more warnings than anyone else exhibiting such behavior would have ever received. He's undoubtedly the most antagonistic person on this subreddit. I don't know how he didn't see this coming.

To me this article is RL clearly looking for a way to get back at mods.
