It had our RBL checks confused, that's for sure.
RBL servers are expected to return a response in 127.0.0.0/8 range for a positive response.
If the domain is resolving to parking page, the response is not in 127.0.0.0/8.
Why don't the RBL querier reject such invalid responses?
Sloppy design, sloppy code…
