Had post deleted for less than 30 post. Why when was it changed?

hi i used to be on here more frequent but busy for a long while then had my swappin and sellin post just deleted for not having 30 post????? i have sold on swappin and sellin before and wonder if my old post were also bumped off due to age? so now my post count is low? also when did the new 30 post rule come in, i just seems like alot as most things i have a need to know i find out faster elsewhere or i dont need help with.

with that said if i cant post for sale dont send any more fund raiser emails till i can

A lot of things changed about 10 years ago including the requirement of 30 days membership / 30 meaningful post in order to sell in S&S.
