The way the chat system is setup would make it a bit more difficult to 'swat' legitimate players anyway. This report option would only be available in the chat window, so you would not be able to search for, and then report a player for RMT. So you would have to get a lot of people together in the same area, or get a lot of the people in your area to register a complaint. What was not touched on, but probably should have been considering your post is it would also penalize people for falsely reporting RMT in order to 'swat' someone offline. While the person 'swatted' may get a up-to a 24 hour suspension because of this, once a GM were to investigate and find that the others did this maliciously in order to harass another player then those involved in the harassment would have their accounts suspended for at least 72 hours for their first offense, and then increasing the suspension time to 1 week for the second offense, 1 month for the third and finally a closure of the account for the fourth offense.

So as you say 'swatting' could be done, but it would have severe consequences as with with almost every level there is a GM review of the action taken by the system.
