I'm not encouraging anyone to use this by saying this but WhatsApp traffic it's encrypted and the traffic through the socket its also encrypted, I guess you can't get in trouble for sending and recieving lots of weird messages? Again, intended for educational usage

that's a lot of words to say "yes, an overzealous prosecutor could try and make a case using the CFAA", but that's because the CFAA is a bullshit overly-broad law. that it's bullshit doesn't change the threat to the prosecuted, unfortunately.

you are totally right

not CFAA concerns, but you'd probably be in violation of the WhatsApp TOS: "… (d) interfere with or disrupt the safety, security, confidentiality, integrity, availability, or performance of our Services; …"

disclaimer: IANAL

Yes, in the own project there is a disclaimer that using this software might get your WhatsApp account banned so use with caution, and anyways is just a fun project for educational purposes. But good to know ofc
