Much as I love disemvowelling, I can understand the problems with many languages and the fact that it's hard to reverse for comprehensibility. I do like the idea of "collapse this comment" as a journal/comm owner option; that seems a terrific way to hide spoilers or potentially offensive content without turning a conversation into swiss cheese. An ability to tag it with a warning--maybe a 25 or 50 character limit? Dropdown seems unlikely to have enough scope, but if that's a server-load saving option, maybe a small collection of options?

Ideally, the collapsed comment would be collapsed even if the thread around it was expanded & need to be opened individually, but I could understand if that took too much special coding.
