Sometimes accompanied by a two-day ban from the TBGs,warnings are messages brought on in a user's profile, under "User activity". These warnings, and any details, are visible to the public through these warned users' profiles. Warnings range from one (1) to three (3) points, and by definition expire fourteen (14) days after their issue.
Bans, overriding bans assigned by warning points, are occasional accompanyments to warnings that may last from two days onward. Bans are used, of course, after subsequent warnings - or a critical offence.
