I have updated OP with Spazzer's list they have begun to compile. The most notable site being thepiratebay. I cannot remember the name of the news site, but it was one of the first when I was searching about Lightning or Segwit (Can't remember which, was researching both that night). It was so bad, that I could not read the article on their site; I had to Copy+Paste the article into a word document and close the web-page, because my computer was lagging/fans were speeding up.

Most people I know do not run antivirus software, but yes I believe some companies are flagging some sites.


Witch hunt! 

I don't know exactly, but Spazzer has a thread suggesting ways to block these scripts : https://bitcointalk.org/index.php?topic=3123275.0
We can possibly contact the site owners or developers for discussion about their use/abuse of browser mining. We can avoid the sites, we can create better scripts to block their miners; the list goes on and on and other people may have a better use for this than I do.
