OT: what are these

I don't know what these are. All I've found online is a few posts where
the writers are speculating these usenet index files and the rar
archives with the cryptic names may be an attempt to thwart the people
who send out DMCA takedown demands to usenet indexing sites. This
approach would make the MPAA have to download the file before they could
find out what's in it. This would be a lot slower than looking at
something like doctor.who.s07e10.720p.mkv and knowing instantly what it
is. I guess the could be backup files. I hadn't thought of that.
Encrypt your data in rar files, include lots of par2 files and post your
backup to usenet. A usenet account can be had for $10 or $20 a month
and the backups are good for several years. If the usenet server you
pick goes out of business, sign up with another and get access to your data.
I think I'll download one of these rar files and see if I can find out
what's in it.
