Please lock the thread. Thanks.
Why? He asked a legit question and haven't received ANY valid answer to the question he asked.
Well, the question OP has asked, it's the goal of merit system. Theymos implemented merit system to encourage users create quality & useful post. And I believe most of user who know about merit they know also intention of merit system. It's not something new, hundred of post has been made about it. There is more better discuss if you search here.
There is two reason why I request to OP for locked this thread. First I am assuming OP just want to gain some merits by creating
merit related thread, because most of newbies are thinking this is a quick merit earning method (may be op intention is good, but who know). Second thing is, this thread would encourage more spam. That's why I had not feed OP. I will suggest OP, be more active and try to search before posting, if you were active on meta then you should got your answer a while ago.
As a merit source I always want to encourage (by sending merits) newbies to make good post. I really do not expect a high quality post from them. Whenever I can consider a post at least as a good post then I try to send a merit, so they would more active and could make more good post. Op could do same, nothing wrong to promise them but most likely it won't work. They already know that it's possible to receive merit if they make good post, isn't? So who are preventing them to make good post?
The thing is that the way I understand the question of the OP is not generic about the merit system but specifically he is asking if he can say/promise in advance that he will give some merit as a reward for some type of post/activity... which I assume it would be of some "quality" (even if subjectively) as expected. I don't think he meant to promise giving merit for just posting random shit (as some replies here are assuming). I also didn't assume the OP was creating this thread just to gain some merits.
Maybe I am being naive here, but I try to give the benefit of doubt... when in doubt
I always try to check post history of newbies to check if I see something suspicious before replying... but in this case he mostly posts in a foreign language and I couldn't be arsed to translate it.
Anyway, considering the OP is not a merit source, and his current rank, the amount of Smerits he may have available to give is almost insignificant. So I don't think it is such a big deal what kind of "experiments" (as long as it is not abuse) he decides to try to encourage quality posts in his local subforum.
And if what he specifically meant is running some sort of "contest" in which the best answers to some Bitcoin related questions are rewarded with merit: Yes, that is allowed and in fact it is usually done (ie. The art contest and many others).
