What have your experiences about this been? Is match fixing considered a common occurrence in leagues you place bets at?
No experiences so far but fixed match are usually unnoticeable so nobody is going to be concerned of it. Again, nobody knows when or where will match fixing happens and with that we never know if it is pretty common to the league or not the least we can do is to suspect an unusual game to be a fixed match like when we see a stronger team being beaten pretty bad by worst team.
