Hi,
Instead of the weird behavior, refiring to the deletion of the list without the knowledge of the users and expose their privacy. It could be more appropriate to redirect the list to a trusted filter list as EasyPrivacy from EasyList repo for example.
I mean adding
! Redirect: https://easylist-downloads.adblockplus.org/easyprivacy.txt
or at least, replace the list title of the filters list
! Title: ⚠ EasyPrivacy, DEPRECATED and no longer supported
Thank you.
