Legal Question in Technology Law in Florida

Illegal may not be the right word. Most websites are governed by terms of use that will prohibit this kind of thing specifically. That exposes you to a claim under contract law. If you are copying and then distributing anything that can be considered protected under copyright right or trade secret law then you are exposed that way as well.

Lastly, there are always common law claims such as unfair business / trade practices / competition, etc. that could be brought as well.

Hope that helped.
