The letter of the law, and the spirit of the law.

[Piers]

It seems obvious that Empire are happy to allow their own T&Cs to be broken in an effort to increase their total MGR at the expense of other Party skins.

Maybe the T&Cs are imposed on them from outside? Whatever it does not strike me as a particularly big issue.

What does appear to be true is that there is some aspect of internal Party politics that is sensitive to rakeback. Personally I say stuff them. Political censorship is usually pretty silly.
