As I see it, the Gay Adult Industry Forum is so active, that a life-cyrcle of an ad stands on less than 24 hours, before getting barried in the back pages of the forum (just like in google, noone searches results in more than 3-4 first pages)....

So, on this forum, since the life circle of these posts is about 24 hours at most, I don;t think it is spamming if I place my ad (i.e. looking for buys) once every month or so... I don;t do it every day, not even every week.... I never even thought for a second it can be regarded as spamming.
