Non-disc,
but as I said in that discussion post….
Some of the stuff about the recent Social Media fiasco has made me think of this issue from a more PR-standpoint. While the reasons for people are varied, I am getting a sense that some users see Staff as some kind of authoritive Big Brother when it comes to content on the site. That kind of perception is hard to shake once it's earned.
So deleting troll posts (and then the ban that's probably going to follow) is only going to strengthen that perception. From anyone who didn't see the post in question, all a user will need to say is "those dumbfucks banned me and erased my comments because they didn't like my opinion!", and there's a good chance that they'll take the troll's side. Sure, we can point to the procedures, show a pastebin image…
… or just -snip- and say "Hit 'show more' and click on their first revision". A troll post is going to be obvious, and leaving the post there after blanking is proof enough for anyome who's curious that Staff had justification for said blanking.
The trolls we're getting now aren't just run-of-the-mill shitstirrers; those that target 2721 likely have an agenda they want to push. And outright deleting their offensive posts only feeds into that agenda, "They say they let people have their opinions on 2721, but they don't. I left my opinion, and they banned me and deleted my post!" is a much stronger argument to make if obvious troll posts are deleted instead of blanked.
