Well there is a thin line between friends supporting you and people trying to build vote-for-vote or vote-buying communities. There are whales who will downvote overvalued content, most notably @berniesanders and I have to be honest 20$ on a multiple 1-line comments does seem a little missvalued.

Of course you have the benefit of the doubt as a new guy, but you should tell your friends to keep their horses calm and only vote your posts or at least lwer the vote on your comments.

I hope you have a great time here, I will be watching you muhahahahhaha ;)
