The coinhive creator put out authedmine for those interested in using
   an opt-in JS miner in their websites. Seems like a fair use of a JS
   miner to me.

   This info might be useful for those that don't totally block

   JavaScript in their browser, but want to be sure to block the new

   influx of JS-based miners (eg coinhive).

   I came across the list in a discussion of the new quad9 free DNS

   service (at 9.9.9.9, hence the name), which supposedly blocks the

   resolution of malware / botnets / "bad-guys" / etc, but is not

   blocking any of these sites serving out JS mining code. I'd be

   curious to know what anyone thinks of the quad9 DNS service.. I've

   not turned it on yet anywhere, but will probably play with it at

   home soon..

   Anyway, the list of sites serving out mining JS lives at the

   following:

   The fellow who maintains this list has a little makefile one level

   up that will add each host as 0.0.0.0 to your /etc/hosts file, if

   that's what you would like to do with such a list. Details:
