Right, this does indeed seem to be a new fad to gain money and be a general ass when hosting by non-gm's.
Next time this happens please take a screenshot and inform us and we'll look into it, if you like you could just pm me the screenshot and i'll have a word with the guy.
however, nudging oneself in a betting server every once in a while is fine, doing it every match is not.
As for betting servers hosted by non-gm's, a lot of the time they're fine, the better ones tend to be done by clans, player owned ones are the ones that have problems.
But yea, just shoot me a pm if this kind of thing happens again o7
