How can a newbies get 103 posts in 3 weeks and start scamming people here?

Answer: thats with the help of such posts as "the never ending word associating game" - its easy to get 30-40 posts a day there.
Maybe we are all part of a team helping scammers to get the min req for posting fake sales within no time, giving all users the impression that everything should be fine.

Would it help, if sellers need to get a "ID number" from a mod which is only available with prior VIP membership with registered real life address, proofed by postal identification?

I know, I know... "Who shall perform this effort?". But I find it very strange that one can join the community, boost 100 posts in 3 weeks and start scamming colleagues here.
Whom shall I trust now in the sales section? I think, the post count is no longer a good index for this.
