Thanks for sharing, if he use the same post on multiple announcements just report all of his posts via the "report to moderator" link. if they are enough reports on his posts the mods taking some action.
I don't get it why there are still devs / marketeers are still using those shit. when i read an ann, i notice in an instant if there are some bounties or bumping services used. 99% of the posts are shit.
