It seems that even though people keep trying to use CFAA for scraping it almost always gets thrown out as long as the source is publicly accessible. Even if the ToS prohibits scraping explicitly.
Seems people have had more luck with just plain old copyright.
But back to this tool in particular... depends entirely on what you are using the data for. Don't use it to gain access to data you wouldn't normally have or give other people access to data they wouldn't normally have and I can't see why CFAA applies.
