Why are there statistics on a non-existent affiliate site?

Question

Partnership programs

My affiliate site with links to projects of the gaming affiliate program has not been there for half a year, in the affiliate account there are statistics on registrations and accruals - 50% of referrals, I can still understand the accruals, there are 5000 refs - they will get it, but where are the registrations from? Cash PS or affiliate program creates the appearance of activity on my account and this visibility was created even when my site was alive?
Where can I see the cache, can I see a copy on the network of my old site?
ps There were 5 languages ​​on the site, registrations are based on English versions of games.
