A large percentage of those bots are in DHCP'ed cable/dsl blocks.  As such,
there's 2 questions:

1) How important is it that you not false-positive an IP that's listed because
some *previous* owner of the address was pwned?

2) How important is it that you even accept connections from *anywhere* in
that DHCP block?

(Note that there *are* fairly good RBL's of DHCP/dsl/cable blocks out there.
So it really *is* a question of why those aren't suitable for use in your
application...)
