Disclaimer: No offense to the thread starter. Just using this as an example.
Now is this not a perfect example of why we should not have any post count restriction on the market section. Till now he has been posting only in the non-tech sections, which is laudable, since he apparently doesnt have anything useful to add there.
Now that he knows how to get the market section access, will he not go ahead make those useless 15 posts. He is forced by the system. Then we will come out whining that TE is getting spammed. If it were up to me I would have removed the restriction long back.
As I see it we have two sources of spam. Market seekers and ignorant new members. Market Seekers will always spam, as they must. Ignorant new members will at least settle down with time.
