The porters are stalkers.
Good lord did I hate those creeps. I downloaded the "Less Creepy Porters" mod, just so I could stand being a guildie. Xbox users could simply kill them, although that might be somewhat out-of-character. Then again, I think even Mother Theresa would eventually kill a fighters guild porter if they acted like that IRL.
A note to the OP: I feel your pain, but perhaps it's time to svck it up, go to a dungeon, and train your blade up from 50 to 70 the old-fashioned way. Then, at 70, stop by the fighter's guild and pick up the referral quest to Alix Lencolia, which I'm dead certain you do NOT need a guild membership to obtain.
