You have flamed us since we are these "people" you speak of. So i'm going to give it to you straight.
Stop being so damn nosy and minding others people business as it does not affect you unless you invite the no skilled idiot to a party(which then you can still kick them). You know what SE have for those that afk leech? it's called the "kick" button and it's a very amazing feature. As soon as an afk leech is spotted do not hesitate to use such godly powers against them.
edit: Once SE start charging for accounts a lot less people will exploit this. However their will be some and the fact still stands it doesn't affect you. The economy won't be overrun like the RMT which is a lot more important than someone AFK and a sucker allowing him/her/it to gain xp.
