Recently, I've been seeing numerous disparate hosts asking for /ip,
temporally coordinated in a way that makes me reasonably sure it's a
botnet or something like it.

I reported a bunch of them.  Nothing happened.  I reported a bunch
more.  More nothing happened.  So I've added two more abuse-reporting
addresses to my `broken abuse handling' list.  (All APNIC, curiously.)
I've now got 49300523 v4 IPs - about three /8s worth, though they're
not nicely clumped into three /8s - in my manually-maintained border
blocks.  (For the curious,
{ftp,http}://ftp.rodents-montreal.org/mouse/misc/border-blocks/ has
files giving the full list: a README and one file each for v4 and v6.)

In a way, I'm grateful to them; they've let me find some very badly
behaved (with respect to abuse report handling) providers at relatively
low cost.

I've been tempted to set up something like that, but it seems to me
that for my purposes it's more effective to border-block them; I see no
reason to talk to botnet members over any protocol.
