From Legacy Wiki
The Legacy Police Station is where Legacy TOS breakers go. If staff members catch you breaking these rules, they may ban you from Legacy, and your name goes into the Police Station with the amount of days you will be banned next to it. If you are banned more than three times, then your account may be removed.
The police station, however, is not just for the people who break the TOS. Players who are going away on vacation or ask to be banned, for example, for a medical reason, can be banned so their accounts do not get deleted because of their absence. Though if your account has a permanent subscriber feature, the chance of getting a holiday ban is low. However in 2009 Staff got told to refuse Holiday Bans.
The station also shows the staff list. This list shows Moderators and Guides. Police Station changed in Update 1.7.00 and Ticket Help was removed and placed in Quick Links and the Community tab.
