Manually enter names to blacklist?

[Rongway]

You cannot; they took away this functionality when they added world visit. Only the /tell command retains the ability to use manually typed names. All other slash commands now require a target or mouseover.

You have a few options to work around this:

• Pick up a petition to start your own FC. Even if you never get the signatures for submission, beginning the process makes you an invalid target for invites.
• Ask the person to stop. GMs should then do something if the player continues to do so because you've asked them to stop.
• Ask the person to stop, then block them from the chat log.
