See, I understand where both people are coming from.
I made a farmer just to be able to afford my builds. I don't mind if others come and door sit, I only do it for SG mates though, and my main requirement is that they do not ghost the minute the "C - word" (Content, potty minds) comes up.
If you are actively playing your toon and just need to get money for your builds. I have no problem farming with you, contribute or don't. makes no dif.
If you are just PL-ing and don't even know how to get to other zones, how to use contacts, or become mute when asked if anyone is available to run TFs... then you bet you butt I'm not letting you in my farm.
The game has rules and often Farming is just a way to make affording things a bit easier. It is not there to take the place of the game itself.
