How to remove BTN undeletable cookie from chrome

[fraudman]

Recently I found out that everytime I cleared my cookies and restarted chrome after checking the cookie data there is still cookie from BTN left. How to permanently delete this supercookie?

Make sure you're telling Chrome to delete all traces "from the beginning of time" (as opposed to the last hour, day or whatever), and don't have any open BTN tabs that may immediately be setting the cookie again.

If it still returns, please send me a screenshot of it.
