What if people vote down my question(s)/answer(s) and then I lose some rep points (below the level required to vote up), and the privilege of voting up goes down the toilet with it (until I regain the reputation points needed). Do the up-votes I already gave other Q&As disappear, lowering back that user's reputation in the process (I mean the author of the question/answer I voted up)? I think the answer is a bit self-evident, but I can't be sure.
