What a great idea. As an appreciation for newbies in contributing to the forum. they will be even more excited to write great posts. whether the winner is by vote?
Ok I just noticed this user now: https://www.altcoinstalks.com/index.php?action=profile;u=77094
4 posts, 8 karma, sign up in November. Not even sure why to be honest, 3 threads out of 4 posts though, that helps. 8 karma for 1-3 topics? Probably.
By my own suggestion then this user would win statistically. Therefore a vote sounds like a nicer idea 
This is karma farming. 4 post, 8 karma (not acceptable)
Why you think this? Where #Proof?
Personally I'm starting to believe, finally after a few years, that this forum is
actually welcoming towards newbies - as long as they aren't spamming or burst posting etc.
Each of the topics were reasonable, each generated considerable discussion. I wouldn't be surprised at all if only one of those topics got 8 karma.
I already posted elsewhere that good quality topics that generate good discussion is worthy of 1-10 karma, and I believe this proves my point. My guess would be "
Bitcoin is amazing". A simple but effective topic for discussion, it's not common newbies contribute value to the forum so quickly, usually they are just replying to posts trying to "blend in" with the higher ranks, hoping karma will come there way too. Instead, this newbie goes out there and simply contributes value, un-concerned of blending in it seems.
Also, that 8 karma is now on 9 anyway, I doubt someone has been farming karma to a new account, as the account is only 15 days old. This means that in these 360 hours, a karma issuing account would of only been able to give karma
only 3 times. This means they would need
3 high ranking accounts to get 8/9. I highly doubt from this mathematical reason alone, as well as you'd expect a small farm of newbies with high karma if this was happening, not just one account in my opinion.
The fact that newbie has posted 3 "successful" topics out of 4 posts, is a great contribution to the forum more than anything and is worthy of consideration.
