I'm of the mind that once it's out there, assume everyone has read it; then there's no point in having the information removed. Probably best to just change your plans and just treat the situation as misinformation.
I disagree.
For one thing, if it's no longer there, it cannot be replied to or quoted, and those who have not yet read it—which, depending on the speed of the scrubbing, could be a high percentage—will no longer have the chance to see it.
This is as true of inflammatory language as it is of "leaks" from IC.
