All the (reasonable) interpretations point relatively in the same direction. Although I do think saying "Trolling is defined as [...]," "Flaming is defined as [...]," etc, isn't a bad idea.

I didn't know what the word trolling was when I first came here.

Any abuse of forum rules by a moderator should be reported to Reggie. Anyways, "Reserve the right to" is just jargon for "We can".

Deletion of content is very rare (usually only used for illegal material, spambots, censor bypassing, and almost never trolling/flaming.) Therefore there isn't really any reason to discuss said content.

Usually when a volatile thread gets closed, that doesn't mean discussion has to stop. It's just a way of saying that particular conversation got out of hand.

(Sorry I quoted out of order.)
