I'll start off with Greg Dukes original suggestion, which I heavily agree with and want to expand on

*Instead of having a name they should have a number based ID that is given to them upon joining after a restart.

So for example P1 joins server after restart has ID 1 P2 has ID2

P1 leaves the server while P3 leaves but P3 will still have ID 3

Server restarts and then P3 is first to join and gains ID 1

Or.... a recognise system?*

Bandanas, Facemasks and Ski masks

Adding player IDs would still allow players to report those who are breaking the rules. But in my opinion, keeping player names above heads would be beneficial as it would serve a purpose for face coverings. Once a face covering is equipped, it will disable players from seeing their name and ethnicity. Making it harder for people to identify those who rob, raid, or commit crimes. There could also be different designs and colours for face coverings. The "Custom Materials" feature could also be used for custom designs made by specific gangs or players, allowing players to display their gang affiliation. Overall, Face coverings would promote more organized, systematic crime and more fun RP for all.
