That is difficult to believe. So you can earn money this way? That he doesn't use it himself may be somehow understandable. If his account is blocked, or they don't pay him, it costs him money instead of making money from it. How many seconds advantage do you have with your stream compared to a quote from a bookmaker? Average I mean. Is that enough to place a bet if you already know who scored the next point ?
I use bookies who withdraw money no matter what. Limitation only means, that they won't accept my next bets.
Average advantage is worthless to measure. If you have i.e. Tennis tournament that my stream covers, you have to be ready on different advantages. It depends on umpire in this case. I don't want to talk about it, because I see that you have no idea what courtsiding is, but it's ok. I don't blame you there, this is why I told that I can prepare video.
