It's best to stay away on these type of games unless you're an insider IMO.
I'm also likely to stay away from this type of games unless I'm not really aware of it and it tends to be like that. But for those professional bettors that has been in this kind of setting, aware or not, they wouldn't mind about it. As long as they can continue with their plan, bet with each match, depends on the odds or base on their analysis, they'll just bet as is. I think that's the perspective of those bettors that are really experienced in sports betting.
