You didn't name the offender. I did 3 years ago which got me a WGT reprimand and put me on forum moderation for 4 months.
I slammed the offending owner on his wall, along with a couple of his directors, and it went away.
Best I can offer.
That said, no contracts here. Strong club, your members will not leave. Actually, they will will tell you about it which is what happened with me.
