They're not clones. Just proxies so they are down too.

This is usually done to make it harder for the courts to force providers to block these sites. Whack-a-mole..

PS: Why am I getting downvoted? Try clicking on the links, you will see the same goodbye message.

Edit: Oh the first 2 do seem to be clones, now I understand. The rest are proxies though. I do think even the clones basically skived off the original's database though so I doubt they will have much going forward.

Did you actually try any of these yourself? Some are clearly clones, and are not down.

The first two are 'clones' but they seem to have just taken a backup of the actual rarbg content from a few days ago (last torrents from the 25th of May!)

Not even, they cloned the UI but (some of) the torrents are stuff that never was on rarbg
