BS. It was Mindgeek's record-keeping failures (utter sloppiness) with pornhub that caused tons of problems, and it was after that, when credit card banks refused to process payments for subcriptions to MG sites, that they "temporarily” purged older stuff from the SC site.
When a company (MindGeek) has a deal negotiated to buy another company (SC), it's given access to all records of the company being bought. If there was a problem with SC's records, they should have found it during their "due diligence”. More likely, the SC archive purge was a stunt/shortcut to appease the credit card cos., and MG didn't want to invest time or money into doing anything to restore older scenes believing that its formula of pushing out poorer quality stuff at a rapid pace would drive more subscriptions.
