Apparently, the "Security sweeps" thread has been deleted. The last post I've seen by mail was by pierolitfiba an hour ago, on 28 Jun 2016, 1:44:56 pm PDT.
IMHO, it's the first time that a thread, opened by a mod (Icon) (!!), has been deleted - it happened after about 1,000 posts, when possible actions of some of the blocked players were discussed in public.
Mind you, it wasn't just closed&blocked but it was deleted, and all the postings are gone (seemingly).
Disclaimer: Don't restart the same discussion here, after a long time it seems unwanted!
