I get what you mean and I had the same concerns before being IFATC. I wanted to freely control airports in the TS because I wasn’t dependent on anything and I was controlling on my own.
To those who are repeating “be an IFATC”, this is not a solution to the problem. The topic deals with the training server and not the expert server: you’re giving to the person who posted the topic an alternative, not a solution.
Now, when it comes to the problem and the solution you’ve presented, let me first of all tell you that anyone that is trolling, even on the TS, can be reported to a moderator and be disciplined. This is something I’ve learned recently before applying to IFATC. In other cases, you unfortunately need to work with them.
I don’t think that it would be possible and 100% safe to make an automatic system to sanction people who don’t follow instructions on a technical point of view. In addition, the TS is the first server where you’ll have ATC and, therefore, it’s also a server where you could make mistakes so that you can evolve later. That’s the whole purpose of the TS: make you - as a pilot and/or a controller - evolve and strengthen your skills!
That’s why I’m not agreeing with your suggestion to sanction people who don’t follow instructions. Because it would be technically difficult, if not impossible, and because they might not do it on purpose.
