First, it harms their anonymity. If only one person has me blocked, then I know who it is.
Secondly, your system is not good enough not give me a space when it's an anonymous asker asking who has me blocked. I end up typing what could be a lengthy response, which I then cannot post.
Please either fix the system so that anonymously asked questions do not apply the blocked list, or do not give me a space to type in a question that cannot be posted.
