For Rules of play:
a) Use of third-party tools
It should be clarified that VPNs are not allowed on the servers and are counted as a third-party tool. I would not think of a VPN when seeing a rule that says no use of third-party tools unless told so, and most others would likely not think of VPNs as well. Many ban appeals are due to VPNs being banned and it seems that almost all banned players do not know of this rule.
This clarification would be logical to implement and would avoid unnecessary explanation by staff.
