I believe one of the reasons to downvote is "spam" (they don't specify what kind of spam either) so yey free downvote pool soon!
Also to the people being all like "hey it's something and it adds up after a while", no, not it doesn't, shut the fuck up and don't accept that spam.
Well, I suppose if you're really slow at math, then yeah, I can see how that could be appealing.
but, but after 1000 spam messages I will have 1 SBD! :D
