[FEATURE] Blocking players by ID

[Unbaloav]

What problem are you trying to solve?

There is sometimes a problem with people cheating by spectating with a second account.

Describe the solution you'd like

I would like to be able to create a list of player IDs making the players on it unable to join, nor see the servers you are hosting in the lobby list. (So that they hopefully don't even know that they would need a new account to join)
Secondly it would be great to get a notification if you are not the ST and someone you have on your list is already in the server or joining the server. (Preferably with a description you have set yourself, for why you have blocked them.)

Alternatives you have considered

Banning the account entirely isn't really an option, since they could easily create a new one.

Thanks, for the suggestion. This is on the to-do list, for when we get more "social" tools into the app, like friend lists and user profiles. Unfortunately it is also quite the big task, so I'm not sure when I'll find the time to work on it! But it is definitely on our radar.
