Parsing links

I have a problem posting links from the "Naughty America" site which should be OK as far as I am aware.

The following link will have changed during posting from (without the stars of course):

h**p://tour.naughtyamerica.com/scenes/austin-taylor-monroe-valentino/10265/?&nats=MTAwNC40LjguOC4xNTkuMC4wLjAuMA

Premium Link Upgrade

Is this some sort of board parsing mechanism? I am not sure if other type of links are affected in this way. This only seems to happen once the post is submitted, they seem unaffected during previewing.
