The only way to kill the list in the first link you provided (other than from that link) is to delete

Of course this will delete ALL of your Flashplayer settings which is fine if you don't have sites you want to save

you can also add

[*Adobe Flash All Site History]
Warning=This will remove all sites from Flash Player's Settings (Trusted sites, Privacy, Storage and Peer Assisted Networking). There is no way to exclude sitea.
