Import error at entry "pgl.example0101" from pgl.yoyo.org

I am using your Hosts ‘conglomerate’ in conjunction with uMatrix for a while now, since Malwarebytes decided to close-source its “HpHosts” file and forcing me (and others) to look for an alternative. With exception of “Malware Domains”, I was also able to deactivate all of uMatrix’s preloaded stock filters (whose servers are unreliable at times) thanks to your unified file, so thanks for your work!

I was wondering for a longer time now why uMatrix is still using one single entry out of Peter Lowe’s server list, when your hosts file is simultaneously active. After a while of comparison work today, I’ve figured out what causes it. In Peter Lowe’s original “upstream” file (https://pgl.yoyo.org/adservers/serverlist.php?hostformat=hosts&mimetype=plaintext&useip=0.0.0.0), there is a entry called pgl.example0101, in your hosts file (https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts), it gets displayed as pgl.example #0101 though, therefore rendering it a separate entry, when uMatrix compares it against the original while looking for duplicates. Did this change happen on purpose, or is it indeed an import error that could need a fix? I am not familiar with this (comparably weird) entry’s history at Peter Lowe’s list, its database entry on yoyo.org (https://pgl.yoyo.org/adservers/details.php?hostname=pgl.example0101) indicates no “legitimacy issues”, though.

@spodermenpls sorry I was unclear. I just don’t understand how this is, in any way, a problem. I asked you if I was missing something, and you replied blah blah. Are we done, here?

@spodermenpls It’s a canary domain, deliberately invalid, there for quality assurance purposes. In this particular case I’m going to keep it in the list, sorry.

Most entries on my list are validated once a week, and are removed after 6 failed checks.
