As far as I know, patrollers can only act on posts written by Newbies, so we can discard that theory.
Correct, as a patroller I can only deal with newbies.
What do you mean by patrollers? Are these human positions, or are they bots which have an API to read and report newbie posts (like Mitchell's spambot)? And when did they start getting used?
This has been a position for as long as I've been on the forum. Think I got it somewhere in 2015 (whilst being a Moderator for the Dutch section) and kept it when I stopped being its moderator. I would look it up, but don't feel like going through that many DM pages.
Patrollers deal with newbies, my bot used to run on my own account, but that isn't very secure, so I made a new one and it got the same patroller rights I have.
But as far as I know, every Mod is also patroller.
You are wrong, simple moderators do not have patrol powers. Patrol powers are given by theymos at his discretion, but initially simple moderators do not have such powers.
Correct. I had to ask for it.
I don't think there is an API, just
patrol.
Correct. All my bot does is scrape, parse, act.
