I was recently playing on a tourney server with NoJutsuMe and GrimmjowMe. I was about to beat NoJutsuMe (Leg was gonna dq) And he pinged. After he pinged he rejoined with in 10 seconds and entered him self when it was a knockout match going on. Also his buddy grim when he was about to lose he pinged on purpose too and rentered. I also have pics if i need them.

How were they able to do that?
