The thing about RMTs is they don't go 100% afk. Either for the reason that
A. They're bot is lv 1 and may die, thus needs to be blood warped back,
or B. They may have to prove to a GM that they are /not/ afk. Most Botters use Windower and sit and surf the web while their bot goes and does its own thing. thus all you're hard work is easily remedied with a five second warp, when they take a moment to check their bot.
I've come to realize the pointlessness of trying to take out RMTs, as can be occasionally seen on the ferry when 10 or so nude lv 1 characters seeking board in perfect sync, cast their lines in synch, and start fishing up stacks of nebimonites. their homepoints are in selbina, and the bot makes them automatically redock, automatically homepoint, and automatically open the door and fix its path if they get stuck on a wall.
Now, if you really want to have fun with the bot, here's what you do.
Shout, "Rayes casts Teleport-Holla" make it look identical to what is shown when they really cast it. Most bots are simply set up to see something in the chat log, and react. Thus the bot should wait about 20 secs, doing nothing... then warp itself. Once he gets back, repeat =D
I found this out when I was chatting with a friend while fishing beside the 10 bot fishers on the ferry. I commented on the fact that my rod just broke, and immediately all 10 of them stopped for the rest of the trip. I LOLed so hard.
If you guys want, I have some pics of me and a friend of mine owning and MPKing hordes of RMT bots, wanna see?
