It'senought.
Merit is trackable, so there is a high risk to buy it, the best way is to publish some useful info.
I was one of the ppl who always publish shit posts for airdrop or bounty program, after the new law, I have deleted all of them, just wanna learn the real blockchain technology, not all kind of tricks, so I'm starting blockchain online course, solidity programming etc. 
In general, what I mean is a new law is useful and effective.

About the numbers.
Actually, I think it's not the issues, number of the merit. for example, could be 1, 5 or 10, then what will happen in the future? every time when we have too many shit posts, we increase the number of merits, I don't think it's a solution.  So 1 merit is  enough,In my opinion, int BTT there are only 2 kind of ppl, with Merit and without merit, this means there are two different groups of people.  What BTT needs is a group of ppl who folow the rules and value their merit.
Thanks.
