Terms of service
The same agreement, at the second address it is indexed under.
There is only ever one agreement. If you have arrived here from a search result or an old link, you have the right document.
Why two addresses exist at all. They were both published years ago, both were crawled, and both accumulated inbound links. The rebuild keeps them because a live URL that has been indexed is a promise to whoever linked to it. What it will not do is let them hold different text: one component renders both, so a change to the agreement reaches both addresses in the same deployment or neither.
