I get mail notifications from IFTTT for new posts on two specific subreddits; they link to ift.tt/ followed by a random, individual sequence of characters which then redirects to the new post.
They usually work perfectly, but today AdGuard's malware & phishing filter blocked one specific link...
I just grabbed some random subreddits for testing.
Using Adguard for Android, premium licence.
Will update post after I receive the ticket number.
