SolvedMarking for global ban - Caused by another player?

I was playing on a random server when someone teleported everyone to one place. Everyone had the default names (George Smith etc.) and I couldn't control my character. Then I received a message on screen telling me I was marked for a global ban. Is this a script-kiddie or an actual ban threat?

EDIT: I'm pretty sure it's fake. There's always a chance though.

Script kiddie. BE won't warn you of an incoming global ban. It'll just come if you trigger it.
