What have your experiences about this been? Is match fixing considered a common occurrence in leagues you place bets at?
In my experience fixing is way more common when it comes to district leagues, college leagues and small-cap games. Not the big ones that get broadcasted all over the globe to a huge audience. These small scale games are the bread and butter for many local bookies and fixers. They will make money from them and not do any other job at all - its the primary source of earning among other strongarming jobs.
Hence if you are betting on the big games, dont fuss about fixing much, keep your mind at ease there.
That's the reason why small leagues has a very small limit because of this possible fixed games. For major leagues, you can bet as much as you want because bookies are willing to accept bets since they know it will attract actions on both sides. The thing is, if in a small league, you know what team will win because you have an inside information about the fix game, bookies are gonna lose a lot of money, so limiting it is just their way to preven that from happening.
It makes sense, right? Because if they don't believe that fixed game is happening, the limitation should be remove since what they want in the first place is to gain more bettors so they could increase the wagers they'll be receiving.
