Heh, I'd suspect that whoever did it was a retard...
And what I do, is definitely oil the seal...and spin it on (because it does, or is supposed to, spin freely) till it stops (spinning freely, as in I actually have to keep turning it by hand), then usually a half-turn extra. If I EVER hear of somebody using a wrench to tighten an oil filter, I will slap them, then make them do the next oil change.
