Searching for Blood Sites is superfluous !!

Inkpot end is level 0 and most other disease sites (except the crown of darkness I think it is) are 5% chance or less, so you can easily build there and then move to another province...sure, it'll kill every 20th unit and waste a turn of research from the rest of them, but the odds of landing on such a site are pretty low and generally not worth worrying over. If the fort happens to be a chokepoint that's awesome, as you now have a nice deterrent to sieging armies. Tie them up with some call of the winds ravens or something else disposable while they soak up the diseases. =)
