Also, then I mentioned people could be banned from events because of their involvement on courtsiding that is exactly what I mean, they are scorted out the stadium if security staff discovers they are transmitting live information on the scores and performance of each one of the players to a third party..
Courtsiding was actually a very viable way to earn a steady income without any risk way back when gamblers initially found out about it, but it's not really a viable strategy anymore since the sites caught on and adapted accordingly.
This is just like any other gambling strategy(Arbing, Card counting etc) that went from zero risk to high risk as time passed.
Casinos will always do well to terminate what ever strategies or loopholes gamblers discover and are using it to make money effortlessly from the games they are betting on, I have no knowledge of what courtsiding is all about in tennis, and will search and read up on it later on when I have some time to spare, but like any other strategy today that casinos don't smile at, I would advice gamblers to simply stay away from what will get them into trouble with the casino they are gambling on, casinos are always on the look out for opportunities like this to use against any gambler to possibly freeze their account plus any money on the account.
So, like I said before, my knowledge is very limited when it comes to courtsiding, and this is because it's only a few years ago I started gambling. Again, if this is something casinos don't like, then lets avoid it.
You stated, "Dude, you are right," in the first sentence. In my understanding and opinion, courtsiding—which the OP mentioned—is not a suitable option for usage in a casino. In what way did I state it? because it can be used for negative purposes as well, which delays exploitation.
The term "courtsiding," since there is a "courtsider," obviously refers to people who attend live sporting events. As if they are the ones who will relay information from the actual live sporting event, just so you know… Dude, you know there is fraud going on. Simply said, I'm not sure whether I understand correctly. I simply believe that these courtiers make use to a discrete device to swiftly send data.
