Keep in mind that this would be a subscription service. It's not as
though the route would be announced to the entire net. If you're not
comfortable with it, don't use it on your network (or change upstreams,
if they're using it).

It's not permanent. There clearly would need to be some means of
human intervention by which an entry can be removed. At worst, a
compromised host is blackholed which will get someone's attention.
At best, it is prevented from contributing to attacks.
