It actually happened that trolls got downvoted even in normal posts

But yeah.
Edit the lowest respect I got on a post was -20. I was necroposting a bit then. O.o (at the end I ended up with -35 respect

)
In total I have 13 downratings, and 3 upratings that got somehow lost in oblivion.

Yeah, I noticed what you said about the troll things. At least that can't happen anymore.
I was also wondering what if you notice a post and it has for no reason an uprating, for example a post that says "Yes, I do" or something? You can't downrate it back to 0.
