Sometimes sites like those have enough info in the url that you can split
it into separate uses/customers yourself, and run different
volume/reputation checking on each separate thing, and that can be useful.

It does seem like that site has a decent amount of non-spam mail usage, but
whether that applies to your users or is enough to care instead of adding
to a blacklist is kind of up to you.
