Board Game Arena

Don't play with them, they perform kingmaking so that only won one of them.

Sorry if this is not the right place

This most definitely is not the right place. Report the player from the link in their profile page, fill out the kingmaking form, and the moderators will investigate. (OK, maybe it's from when you select "kingmaking" for why you are giving them the red thumb. Still, not the forums.)

Okey! Thanks
