This tool doesn't in any way meet the legal definition of fraud. Any if everyone working on online advertising loses their paychecks then that is an acceptable outcome.
Yep, people toss the word fraud around, and lawyers love to use it to scare the shit out of the opposition, but it's a very high bar to meet legally. An automated tool that clicked randomly on web page elements for no financial gain to the user or supplier of said tool would in no way reach the threshold of fraud.
Obligatory IANAL.
