I do not understand the policy of the forum administration. They do not prohibit the advertising of dubious and fraudulent services or companies against which criminal proceedings are instituted in different countries of the world (for example, YoBit Exchange).
There was a time when scammers would be branded with a SCAMMER sub-rank, for all to see, and some of their forum privileges could be revoked. But that was when the forum saw significantly lower levels of activity, so in 2013 theymos designed a reputation system called Trust which is largely supposed to be self-sustaining, allowing him to spend more time on other stuff. A centralized approach to policing scams would require theymos to hire dozen(s?) of full-time mods, probably start charging fees and acting as an escrow, and institute tons of restrictions in doing business on bitcointalk. Basically, it would turn the forum into ebay2. And you'd still see people getting scammed and losing money lol.
