Honestly shocked that anyone would even say this, but even giving you the benefit of the doubt here -- the one case where I could imagine this might not happen would be if you're a police officer investigating such cases. But they also have their own therapists dedicated/trained in police-specific issues.
Even if someone went browsing for it, yes that's illegal but there's no benefit in their therapist reporting them for just visiting terrible websites.
But also there are definitely ways to get accidentally exposed. That's an absolutely awful thing to call the cops over.
