I imagine the answer is that the thread that was deleted was part of a vendetta against a particular poster, which is in breach of the board's rules.
While I'd guess that (re. the original thread Jonathan is "indirectly" asking about now) the "last straw" was my umpteenth dustup with Amanda (GBFH) its worth noting that the thread started as a not-so-thinly veiled attack on Bri, who's not here @ present to defend herself.
And this one won't be either. As a matter of policy, mod/admin decisions aren't up for discussion. As a matter of practice, though if you private message or email us (as opposed to posting a thread about it), you'll likely get an answer.
Reason is poor propaganda when opposed by the yammering, unceasing lies of shrewd and evil and self-serving men.
