Good advice, and I sure hope those presently compromised accounts take the actions you recommend, before what happened to me happens to them. I wish I'd seen this post before that happened =p

Also, I very much appreciate you taking the time to ascertain how my key was availed to the phishing hacker, and clearing up how it happened, as I was mystified at the time. I have improved opsec as a result of what you found, and now copy something to replace the key on the clipboard every time I login. If I ever make the same mistake again, I will not be posting my key.

Thanks!
