Liam Mueller

Frank, I'm concerned about the legality of web scraping. Are there any legal implications developers should be aware of?

Frank Abagnale

Liam, that's a valid concern. While web scraping can be legal for many use cases, it's always important to make sure you are complying with the laws and regulations specific to your country or region. Consult legal advice if needed.
