These sort of questions never make the slightest bit of sense. What you appear to be looking for is tips on winning outcomes in sports because that will make you a profit. However if someone has either through a) underhanded dealing that fixes results to a certain outcome or b) an excellent track record that brings in a clear profit for the individual or group, then they simply have zero reason to include you in their setup. The more people that know or utilize a certain strategy, even if just copying someone else, then the less likely the bookmakers are to give you a decent profit that you're chasing. Besides that, if they are so super successful at picking winners, then it makes more sense for them to just keep on growing their own bank roll than share with anyone from the general public.
