I don't really understand this community. I wrote my first blog about the guy with the most problems solved (in my opinion), and I can see how people could have misinterpret it. I made several edits for it too have a neutral opinion, but in turn got even more backlash. It was neither spam nor trolling. Is there a general rule about blog posts I don't know?

Sometimes I want to rate a blog post on my cellphone and I sometimes misclick, and it registers the wrong vote. Why does codeforces do that? Don't get me wrong, codeforces is really well-built and a good site, but the vote system could be similar to that of reddit (clicking on the same button twice could undo the vote, and clicking on the opposite button would switch your vote to the opposite).

The user maspy has 10233 problems solved as of right now, and he registered ~4 years ago, which means he has an average of about 2558 problems solved per year, which is an average of about 7 problems per day. I searched a lot and couldn't find an account with more problems solved
