agreed. if the reason you get banned for buying an eardweller is that you didn't work for it, then it shouldn't matter *how* you didn't work for it, merely whether or not you worked for it.
so how about if someone pays to have an eardweller farmed, and then just pikes inside the quest instead of outside. same basic scenario, really (and probably a better idea, since it means you've got less loading/run time to get to your eardweller before it disappears).
mind you, i personally would not pay for an eardweller... after all, i know how to farm it for myself, and now that i'm burning all my vendor trash on crafting i don't have as much plat to burn on other stuff (if i do burn plat, it'll be on something like vale larges, probably... but even then, not likely)
