you can experience it just by looking in this forum, why i said that? user can give trust rating to members that they have made a deal and for the added reputation we have the merit system.
i think we all expect to see something a little bit more stimulating than the trust system on the forum, even if the goal is the same

Plus, this forum doesnt use any AI/machine learning to filter out questionable ratings/behaviour
Plus the merit system is very new, untested and many users are not satisfied with it.
I can't say anything bad about that merit system. It's the great way to avoid an acc-selling business...
Just wait until you need a lot of merits to level up, then we talk again about it

And about the acc-selling business: It hasn't changed anything on this, just that the prices are now more expensive for accounts as I heared. So in fact, the merit system helped to get sellers higher prices as a lot of those accounts are hacked anyways and not self made.
for what concerns the sale of accounts in my opinion has not changed anything but rather prices will increase due to the current rank-up situation, it would perhaps be better to replace this system with a repu-type evaluation site that makes level up users really active and useful to community/forum
