That's possible with any RBL. It's a good idea IMO to give any RBL a
"trial marriage" by routing its hits to a quarrantine folder for
review for a while (weeks, at least) before using it for outright
rejection. That gives you a chance to see what the false positive
rate is, and to add them to a whitelist to reduce it to an
"acceptable" level.

FWLIW, I promoted spamhaus to rejection status with an FP rate (after
an initial whitelisting period) of about 1/month. Given that the
rejection message specifies how to bypass the block, that was
acceptable for us.
We also reject based on list.dsbl.org and cbl.abuseat.org (neither of
which had *any* FPs in the monitoring period). We also quarrantine
based on dnsbl.sorbs.net, dnsbl.njabl.org, bl.spamcop.net, and
relays.ordb.org.
