Hi i just joined a room and see 2 players with the same name and the same clan, and when i joined he kicked me, the image:

Pm the image to a Gamemaster.

As I know, it isn't farming 'cause when you play with yourself, you don't get qi at all.

Irrelavent.

1) They can be banned for attempted farming.

2) There is a rule about multiclienting in the same server with BOTH accounts playing.

Seeing how both apply to this, it doesn't matter.

You can't farm by fighting yourself and it's a private server. Not against the rules.
