NO.Maybe if you sell hacks-but not for using...you can only get banned
yup king is right ^^ you cant get sued for using hacks i think you can for coding but no one actually gets sued unless they are selling hacks and so on

Unless you modify and distribute edited copyrighted code, you're fine.
just dont hack nx or anything that costs real money and your fine
