Because 你 asked nicely I am not gonna be a rude asshole to you. 支持 are 给 because a user deserved them if 你 didn't get anymore 支持 people probably didn't think 你 deserved them. 支持 accumulate over time so be patient. And sorry but no I don't want to give 你 支持 because that would ruin the whole idea of it.
No. I would, but that would ruin the idea of 支持 giving. You'll gather them over a time, as Bandit said. 支持 do absolutely nothing... I have over three hundred and it hasn't helped me in any way, whatsoever! XD
