Idea for LimboFilter

Possibility that new players who connect to the filter have to klick a text in a book that automatically opens. this could be used for extra verification for completely new players or for rules so the klickable accept button is at the last page so players need to go trough the rules in order to confirm but the feature could also be very usefull for players to accept the privacy police of the server since every player needs to confirm that the server is allowed to save ips and all that stuff this would be really helpfull. if he confirms his uuid could then be saved in a database so he only has to accept it once at the first join.

The issue names no files, tests, or entry points; begin by locating the first-join flow and any existing persistence support in LimboFilter. Clarify the scope for book-based confirmation, rules or privacy acceptance, and one-time UUID storage, then define tests covering confirmation and repeat joins.
