Yep, a great glitch this used to be. I pulled it off once back when I was more into looking for wall glitches, etc., but they fixed it eventually, so....

It kind of stunk that players could attack you - in that way, you couldn't last very long unless you stole something higher level like a Navy Colossus or a Storm Reaper....
I never did manage to steal a Juggernaut, though. If the glitch were around longer, I would have tried, but at the time, I didn't even know EITC Juggernauts existed...
