For anyone interested in how these resurrected threads happen. . .
Sometimes a new member, in a rush to gain Classifieds access by posting 50 one-liner posts, will dig way back to start randomly bumping old threads. When the Staff catches on we have a way to quickly remove these one-liner posts at the same time. However, if another member posted after the removed post, the thread will still stay at the top, further confusing the next several posters.
That reminds me of the thread about tips on looking at a new Sig. The OP advised she bought a GLock instead, but dozens of further Sig tips keep rolling in, many of them by those sub 50 posters.
