Bot catching monsters, they necessary in GMS?

and yes, how it works is the bot catching monster is aggro-ed by any attack on it (miss or hit) and then casts a magic attack that returns the player to a nearby monster-free map (Usually a town, though some of them send you to dungeon entrances like the Shade)

So a warrior training (or just walking around) with Power Guard on, will be whisked away if one of these bot-catching monsters bumps into him?
This does not sound good at all.

Plus, as mentioned before, what about the poor legit players who don't read forums, websites, or even Nexon's annoucements? They wouldn't know why this monster has this power, or how to disable it.

I don't think we have such a problem with botting that such measures need to be taken.
