Please be more specific thank you, I am newbie at wapka 🙏

If the user is trying to send it wisely like these biscuit . twenty . com then :POST(msg).REPLACE([" . ","."]);

Create a warning page too and do what u want

Maybe try something in all creator like these :POST(msg).REPLACE([["http://","https://","www"],["/warning.html?url=http://","/warning.html?url=https://","/warning.html?url=www"]]);
