This wouldn't be related to an attempt to remove all traces of THE rift, would it? Not a good idea, IMO . . . rather transparent.
Of course, it's ya'll's option, and I can see removing the relevant stuff that might cause the smoldering ashes to re-ignite, especially since those are now moot, unlike many of the missing posts.
There'd be nothing to gain by stumbling across that unpleasantness again.
