Right, so you two decided to keep having some beef - that's on y'all, not on me. I wasn't involved in that at any point, except to resolve the conflict to the extent that both parties were willing.
TSU was at the beginning, and for a long time now has resumed being, simply a curation project. The attempt at making it a "community" in and of itself was ridiculous on my part - it's just a project that supports a few different communities.
I don't really know what you're saying in your third paragraph at all.
If you're trying to make a comparison between people upvoting someone's content, and then not anymore, and down-voting someone's content, it's a very different thing.
Ex 1: I give someone a vote (worth $) on some/all of their posts for a time, and then stop doing that.
Ex 2: Other people are giving someone votes (worth $), and I down-vote it so that they don't get that money.
Good luck
