If you have purchased a "90 verified" voucher from a third-party reseller:

The most plausible explanation is commercial. Many tutorial hubs use codes like VERIFIED90 or MEGA90 to offer 90% off the retail price.

Once verified, refresh the tutorial library. Content previously locked behind a paywall (usually marked "Elite" or "Advanced") should now be visible.

Some platforms implement trust scores. A "90 verified" could mean the user or account has been active on megatut.com for 90 days without a single dispute or chargeback.
