really, the people that have done it to me have literally said they will punish me then write 'over rewarded' one hour later, whilst getting a lot for a very average post. The more you look the more you see it happening to others. I have had it just for defending someone else or commenting on a post or resharing a post they don't like etc. The timing is everything sometimes, but the comments like 'over rewarded' lets it go unnoticed to those not paying attention. It's a real shame a small handful of people ruin what would otherwise be a really amazing and nice community. If you don't like something or someone fair enough, down voting them to oblivion is another. It just shouldn't be allowed IMO.
