If we do implement this, please only do the fourth option. I'm pretty sure we've talked about disemvoweling before on this community, Though I can't find the entry, and I know I'm not the only person who said they find it actively hostile. Sure, those of us to do could avoid journals and communities with disemvoweling, but I don't even like the idea of implementing it.

On the other hand, a collapse of a moderator (or in this case, journal owner) voted-down comment is a fairly standard blog functionality, without any of the emotional issues of deisemvoweling.
