I'd like to add that I highly doubt anyone is going to tag you just because you made a thread self-moderated.  At least not anyone whose trust carries any weight.

Also, there's now a notice at the top of all self-moderated threads that tells everyone how many posts have been deleted, so if you started deleting a whole bunch of them then someone may start to wonder if there was a problem.  Otherwise, you could quote the post, defend yourself if it's an accusation against you, and then delete the post.  Or you could just delete it.  Or you could make a local rule against specific members posting in your thread. 

I agree with your position about not wanting to self-moderate a moneymaking guide thread, since it's best to keep everything out in the open...but there's not much else in the way of defending yourself against people telling lies about you.
