Description

gorhill promised the removal on a condition:

Then just before the one year passes, MDL was updated at Jan. 22, 2020. However, this was just removing one domain from the list (I used WBM https://web.archive.org/web/20191006191919/https://www.malwaredomainlist.com/hostslist/hosts.txt):
https://www.diffchecker.com/1tI1KbuZ
and the list has not been updated for more than 2 months now.
