A direct question relating to these has not been presented, indirect comments have been made however, addressing other subject matter.
PrivacyGuides does not cover URL safety checkers … What are your opinions ?
Personally I use Google Safe Browsing ( Transparency Report ), but do not trust it at 100 % level.
I do use Control D’s service, more beneficial for users, and also rely on Firefox, and the UBlockOrigin extension, as well as an AV/AM product, and lastly have just begun with phishing_army_blocklist.
I am possibly overboard here, but I tend not to rely on only 1 service for something as important ( note some of these accomplish other feats as well and have been added principally for those, but they also incorporate blocking options ).
