I manually check those lists every other day, and then use our abuse

The obvious question, given that you manually check them, and send a
'notification', (You didn't mention when/if you shout it down) ..
How much damage can a threat actor do in a couple of days.. Ouch!
Even if they can get a few days out of it, you have made it worthwhile
for the bad guys to target your networks. Long take down periods are a
systematic problem in the industry, whether a Spammer, a Phisher, a
Hacker, or a C&C server.
And there are a couple of mentions of manually checking lists on this
thread, you can of course use an automated checker that checks all the
common lists, SpamHaus, SpamRats, and dozens of other reputable lists.
That service is offered by HetrixTools, MXtoolbox..
I am sure you can convince management the small cost is cheaper than
your time.. ;)
