I never heard of such a thing. If you buy a domain name (a custom one, not the free one), it doesn't change your free url, it just makes it re direct to the custom one, the only time said url would no longer re direct is if you either let the custom one expire, or your sub domain is one of the ones we ever dis continue, in which case the new free url would then re direct to the custom one still.
Anyway, bottom line is, if you buy a custom domain name, your free url will re direct to custom one until that custom domain name expires.
As for the list, the entire list as of now, is in the topic Ape linked to above, in the spoilers is ever domain name we are either going to be doing away or already have. Whenever we decide to remove more, we add them to the list and then post that the list was updated. In that way you will know if a sub domain you use will be going away, assuming you check the list whenever it is updated.
