Good suggestion.
Thanks, but it will become more than a suggestion if OP doesn't end up making a thread about it. I would happily start the thread and maintain an OP of suggested sites that are accused of doing so. I am unaware of how to search these sites down, unless these add-ons/extensions let you know when it was attempted and I'm clueless. I'm open to ideas on how to verify accusations; It'll get started today, because I really like the idea.
I know that browser mining, at least with the software that Coinhive came up with, was a way to find alternative revenue and I actually believe that it can be very useful for businesses like newspapers or online news portals. I was part of a newspaper daily that had to shut down because people simply preferred reading online than buying the paper. I keep seeing ads and requests to allow ads on some of my favourite news sites, they'd do well to install something like Coinhive. That would probably be the ONLY way I'd ever let a miner run in my browser.
It is a pretty interesting alternative to intrusive ads. I would be perfectly happy with offering up a small slice of my CPU as an alternative to ads, as long as there are restrictions on what they're allowed to do and some sort of regulations of informing your users. A small note at the top of the page, maybe a 5%-10% limitation on my CPU usage or something reasonable.
It's definitely not a conspiracy... there are just too many users out there who don't even know their computers are being hijacked. I've suspected a few streaming sites for sure, but yeah, if a list of them came up, might do a bit more to shame these guys into uninstalling their scripts.
Hindsight is 20/20 for most people, and for others ignorance is bliss on all accounts. Streaming sites have been suspect as well for me. I'm going to start that list myself in a few if OP isn't interested in doing so themselves. Even if it doesn't shame them into uninstalling, maybe it'll at least force some transparency and discussion for this kind of thing.
