Many peoples have been affected by cryptojacking in the past and still getting in the trap of the scammers. It's better to avoid faucets and cloud mining sites as this site's have the settings to mine cryptocurrency in the background which we don't realise early. Good and informative post OP keep up the good work.
Yeah, I hadn't considered that faucets would be likely to do this cryptojacking thing. First places that come to mind for me are torrenting sites, I think there might have been a thing about the pirate Bay doing crypto mining instead of advertisements. I'm not sure which I prefer, considering the advertisements there are awful and in the way of browsing all the time.
