Harvesters had a bad rep cos they were basically terrorists, wanting to harvest all organics. I saw them as a pale copy of another player who RP'd a psychopath, killing everything in his path.
ID can say AI, but the IFF can be BMM/IC/KSP. this indicates that the ship is a drone working for that faction as a haulier/miner/military pilot. I don't really see the problem with this, unless you want to Rp as a 'free robot', then I would suggest asimov's naming convention of R.<Firstname>.<Surname>, with an IFF of 'A.I.'
