Reporting posts is now available in the upgrade, but this is more in regards to people abusing their profiles for spam purposes which is harder to control.
Oh I see, I thought you meant just the bots.
If users are doing this as well then, yeah... maybe a minimum rep requirement that can be over-ridden if a user proves themselves "trustworthy" prior to reaching the 200 rep requirement, since not all users will want to post 200 times just to advertise their project.
If the user can perhaps request early "release" or something, via PM or maybe a thread? Not sure how one would deal with that...
