Hey Josh. We prefer to have registered users than visitors, so that you too can be matched and in order to grow the userbase. That's why we've put some features only to be used after registration. On top of that, these feats are useless as a visitor; the muting will be forgotten when you come back after 48hrs.

It takes literally no more than 10 seconds to create an account, you should give it a go ;)
