The only people whining and defending AFK leeching are just do it themselves, you can justified your actions anyway you like the community is only going to see you as a AFK leecher.
Since people are getting confused or don't understand what this topic is about I'm going to spell it out for you.
Multiboxing does not violate the ToS.
Botting violates the ToS and botting is running a macro or a script that lets you gain sp while not at your screen.
AFK leeching is does not violate the ToS but it lets you gain sp while not at your screen. Which means it produces the same effect as botting.
Not mingling yourselves with AFK leechers, because you disapprove of their methods, would mean that those players would have to use methods that doesn't require other players to get the full effect of the game, hence multiboxing.
