Why can't Badspot run your map on a private server if he wants to? Are you worried he will wear it out or leave muddy footprints on it?
What if the Queen of England looked at a picture you drew, would you be freaked out?
Trust me, nothing bad will come of this. Enjoy that your stuff is visible to other people!
And nice work on the map.
