Registered domain one day, got 23 calls from marketers the next

Has anybody else experienced this lately? I wonder if it is related to gdpr drying up data on older registrations? Any other theories?

Edit: I used Godaddy, didn't pay for privacy. No calls today so far today (10am east coast).

Edit 2: Just talked to a coworker, it happened to his son recently and he registered at register.com. I think that supports my theory.
