Web Rep is a reputation-based voting system. It asks "Do you like this site, and how much do like it (or not).

So, based on the idea that everyone is entitled to their opinion…you just live with the fact that someone/s does not your site. “Like” is so ambiguous, it can’t be malicious. What is your site? If it offers any kind of content that is going to polarize people, this is always a risk.
