If by stats you mean how many times something is read, that's not really relevant since the content is being served by the mirror without Reddit's ads or trackers.

I don't know anything about this particular site, but typically these kinda sites operate on a cached version that is requested just once. So reddit would get a single view no matter how many views your link gets.

For sites like Google's cache or archive.org, they often were gonna cache the site no matter what.
