We don't have standardized ban lengths here, so they're at the discretion of the admin/chatmod imposing the ban, but I would suggest escalating bans for people who ignore repeated warnings. For instance, first one day, then two, then three, then a week, and so on. At some point, a serial offender will either get the message or eventually end up being banned for so long that he ceases to be a problem.
