If I were trying to send someone to my nefarious website, I'd definitely now wrap the link in this, so that the savvy viewer would think it's a harmless verylegit.link...
RequestPolicy Continued in FireFox, and perhaps other plugins that control/restrict cross-site requests, asks for permission before redirecting to superdodgysite.com and safeandwonderfulsite.com. It's not a feasible solution for the masses, but I really like the control over browsing that it gives.

Which is safe and wonderful and which is dangerous?
