That's a great idea! But it can't be a separate page, as many of the sites are single-page variants. A section on the main page should do, but I will have to make it detailed.
Maybe you can create a separate section in the bottom of the page to be used just for seized mixers.
Things that should be included for this is archived link (to avoid original pages getting deleted), screenshot would be nice, and information about exact authority that performed a seizure.
