KneeTheCap: It's possible, I've gotten PM's for "gifting games to a wrong person". There are people who feel that they should receive games, which makes no sense, really.
spoderman: Jealousy, maybe? I have a feeling a lot of this downrepping may have to do with that, though not all of it.
I think it's just people who are bored and want to mess with us so they make a bunch of accounts and go after people who do nothing.
Like me a couple months ago. I had about 600 rep and now they won't even let me get to 230 without down repping me some more.
and now I am at 209 when an hour ago I was over 220 but since I posted that they are down repping me again.
