Is there a simple way to add an f flag to anyone that has been seen in the channel on at least 3 different days(firstseen lastseen and current dates are all different)?
you could keep a log of visits (it'd probably be better only to log the day they visited) and when it reaches 3 flag them.
I was wondering if there was a plugin that already did something similar automatically.
Not currently, but I know a few people around here with too much time on their hands (unfortunately, I'm not one of them anyore).
