I was just thinking, this may be moot.
To get to TL3 one of the criteria is
must not have received more than 5 spam or offensive flags (with unique posts and unique users for each, confirmed by a moderator)
If this is an “all time” count as opposed to an “in the past __ days”, once a member has gotten 5 Flags they will never make it to TL3
@codinghorror is this the case?
