And about 95% of them will be a Dick about it, prob taking it personally & getting all arsey.
Thing is, most of the time these sales posts appear to be from relatively new users, who's sole reason for joining the forum is to use the classifieds to shift their overpriced rifs, prob cos their usually fb pages are no longer allowing rifs, & the likelihood is that they'll not contribute to the forum in any other way, so whether or not we give them a heads up that they're being "outed" is prob irrelevant, they're likely to have spammed their sales thread on every other forum they can find that gives them the same kind of ease of access.
If they're a "true" member, they're likely to see the post when they click "unread posts" looking for new content.
imho😉
