Thank you for this Robert @robertvargic.

Using ghosts as a preliminary check.

Comparing to our main list — which doesn't include porn — the 41,806 domains of this lists intersects at a rate of 13% which seems high.

Robert @robertvargic here's the TLD breakdown of the suggested list. I often find glaring mistakes at the bottom of this list. Only a few errors are evident in this case.
