Don't post anything that could be considered a scam, even if it isn't. The proliferation of scams is increasing and it's hard to tell between real scams and posts that fall in scam categories. Posts that could be considered a scam, even if it isn't, will be removed. If the same person posts a potential scam they will be given a warning. Three strikes you're out. While there are others, the following are post types that are not allowed.
Duct Cleaning - Chimney Cleaning - Husband/Wife got transferred and we have to sell everything - Bogus jobs - Charity contributions - Quizzes - (someone) died recently in an accident... I think you may have known (this person) - Lost dog (animal) scam - Alzhneimer's patient scam
