Thanks for doing the search for me.
I can only remember two serious, personal threats I've received in some 20 years online. You forgot to mention the second, when you threatened to punch me in the face after my initial post to that thread. So am I bitter, or was I so shocked by that disproportionate response that I think prospective users need to be warned ahead of time?
From my perspective, too, I remember at least one valued participant being asked to leave every summer. If this rate has slowed to several years between ocurrences, that may be an improvement or there may be fewer, and more careful, forum participants. For my part, I prefer the moderation on this and similar (some of which are commercial) forums.
