Power leveling services, legit or legit?

Exploit the Software, Cash Items or the Service for any commercial purpose, including the provision of "power leveling" services;

This obviously states that using power leveling services is against the ToS of Nexon.

Restrict or inhibit any other individual from using the Service, a Cash Item (as defined below) or the Software, including, without limitation, by means of "hacking" or defacing any portion of the Service or Software;

That must mean using power leveling services is as bad as hacking. BIG ILLEGITS

Engage in rude, unlawful, harassing, vulgar, obscene, hateful, threatening, abusive or otherwise objectionable behavior, including, without limitation, looting, kill stealing, making sexual comments and/or cursing;

Does that mean anyone who loots someone else, killsteals, makes a sexual comment or swears is illegit too?

Anyway, I'm just curious on your views of using power leveling services. Do you think it is legit or illegit and why? I'm wanting to know what you think about because there are quite afew level 200 players that used these services so are they included as legits?

If you want proof of these ToS, go to the Nexon site and look at the bottom of the page.

edit: By power leveling services, i'm talking about someone going on your account and training you while you do whatever. Not you afking on a rope like most do at Newts and leech exp.
