ban it permanently

I disagree there. Try it. See what happens. Make an informed decision from there.

Anyone upvote his own post for monetary benefits only, otherwise there is no reason to self upvote, this is wrong use of our own power IMO. Which i learned today by reading so many problems, self voting is playing a part in those....
Just tell me why else one will upvote own post? One is sharing because one like that, it already understood.
As i said earlier i agree with you to try it as an experiment.
Later is said ban it permanently, because IMO i am sure it will be the result of experiment.
