You're saying this because Techdirt is manipulating you.
The CFAA is in fact the logical private cause of action for suits to enforce terms of service. It is literally the section of the US code about enforcing ToS's.
A civil suit is a civil suit. CFAA-derived civil suits are not especially more scary than other civil suits. It's scary to be sued by Craigslist no matter what. The CFAA has nothing to do with it.
You should be irritated at Techdirt for misinforming you solely to generate rageviews.
You'd file criminal charges against someone who breaks into your home every night to hurl racial slurs at you and keeps picking your lock no matter how many times you change the locks; why wouldn't you file criminal charges against someone who comes on to your channel/forum/etc. every day to harass your users and uses a number of proxies to change their IP no matter how many times you IP-ban them?
