ЗЫ Adding a character as a Blocked contact will automatically prevent that character from challenging you.
ЗЫЫ There's a couple of restrictions in place to ensure that this can't be used to cause undue load on the server, and to
prevent 'challange-spam' from negatively disrupting someone’s client (similar to the exploit of convo-bombing someone)A player can only have a single outgoing challenge request active at any time. After issuing a challenge, you must wait for it to be accepted or refused (or for the request to time-out) before you can issue another challenge to someone. This doesn't mean that you can't have multiple engagements going on at the same time, it just means that you can't go through the local list and blindly issue challenges to everyone in parallel. As soon as a challenge is responded to, you can move on to issuing the next request, so setting up a 3v3 for example will still be quick and easy if everyone is on the ball.
Similarly, a player can only have a single incoming challenge request active at any time. If he currently is considering a request from one person, any requests coming in from other people will be denied.
Challenges will respect the Block option in the contact list. If you have blocked another character, that character will not be able to issue challenges to you.
