I've join CF for 15 months. All I wanted is just participate in contests, join the community, comment, and learn. But what I receive usually downvotes for no reason at all. I got downvotes because of some stupid comments, well I think I can accept that. But then I commented "C is really interesting :D" about the problem C from the previous contest. It's just an expression, a feeling for the problem, harmless and not even a stupid comment then I got -17 downvotes or even more. Well I guess it doesn't matter anymore I will also get tons of downvotes from this entry anyway.
