I am fairly certain that mprep also uses some amount of automation in handling reports. It might not be to the extent that no human intervention is required for action to be taken, however, I strongly suspect that he uses tools to help him handle common report types quickly -- he certainly has the technical expertise (from what I have observed) to create said tools.
I do believe I remember seeing them say they have a way of handling mass amount of reports, though don't quote me on that.
I reported a couple early in the day, then I noticed they were gone almost as fast as they appeared and I stopped, and just sat back and watched.. That is a very good bot.
Yeah, if your a frequent patrol visitor you'll see them pop up every so often. They're mostly a non problem, since the bot handles them quickly. Though, there's a element of risk still for users visiting, and potentially downloading it, so I don't think it's too much of a problem reporting them. Like I said, I sometimes get rid of them before the bot does, though at Mitchell suggests they seem to come in fits, and starts so once they begin they'll continue for a while, and then die down.
MindlessElectron has nuked over 300 people today. The PhoenixMiner spammers have become very active all of a sudden. The last time my bot had to deal with them was Feburary 3 and that was like 130 of them (and the time before that was January 18).
Do you recall how long this has been going on for? I believe its been over a year since they started, but I think I might be grossly understating that too.
