if there's a plausible canon reason why their character would be a vampire, like say they're playing the malleable protagonist from baldur's gate and they romanced astarion (this even happens in some endings), then yes, i would let them in. i might personally think that's stupid, and i might hate those endings, but it's very possible in canon and i have no good faith reason to deny it.
ships are easily plausible in most canons. if both players are into it, that's fine, and you'd only be rejecting them because you're weird. a potential problem is if one half of the ship drops, then you get a new player and the existing one pressures them about shipping. it's not 2008 and we're not on livejournal and the chances of that happening are low but if it happens you can vent your weird anti rage then.
