Unfortunately, we don't have the manpower (or legal jurisdiction, in some cases) to deal with issues between users.
BYOND staff merely provide the tools to create and play games, and a website to display them on; the games themselves are created and run by users, for users. As such, we don't have any control over their content or management.
If someone is spamming you on your pager, you can ban him by clicking on the pager "Ban" button and adding him to the list. If he is spamming in a game, contact the game's host and see if they can boot the offender. In future versions of BYOND we will implement controls to make this easier for the host.
If a host is being unfair to you, your best bet is to boycott them.
