Please email info@archive.org and request that they remove exclusion from their site.

As you can see, either someone from Sellix requested the site to be hidden on Wayback Machine, or the Wayback Machine admins hid it themselves, perhaps because Sellix used to be more lenient with selling stolen accounts and such a couple years ago.

If you email them from an @sellix.io email, they should un-hide the domain.

Wayback machine is a good thing used for many legitimate uses. You don’t see any big websites excluding themselves from it. Also, Sellix can and has been archived on archive.today, which doesn’t honor requests to hide your website https://archive.is/*.sellix.io

Hope to see Sellix on Wayback machine again soon
