Maybe there should be more discussion about these types of cookies (most aren't even aware of them or their capabilities), how to PREVENT them - to extent possible & how to clean them up. They are NOT easy to get rid of if they've been placed in many / most of the known locations they can hide.

Also, FAQ on them. I read the design links for New Identity & the bug links, but I didn't see how that handles ALL the known locations where evercookies can be placed. Another view is, "An ounce of prevention is worth a pound of cure." I think educating users how to avoid them, to the extent possible, would be good. They're often easier to avoid than eradicate.

I can't vouch for these clean up utilities effectiveness on evercookies. I use them, but haven't tested much on evercookies.
BleachBit claims it will clean evercookies (recent versions).
CCleaner (some forum moderators) claim it will clean them, but I couldn't squeeze out of anyone at Piriform, that CCleaner officially claims to handle evercookies (meaning, all known "hiding places.")
