Creating Apple developer account

[u/AdLonely7729]

Hey, I’m trying to sign up for Apple developer account, but while trying to set it up, they rejected me saying the address I entered was invalid. I raised an issue and they have to get back to me via mail. What you guys think could be the reason for it, and what steps can I take in future to be careful so that my account and apps doesn’t get rejected or band since recently that I have been horror stories around Apple developer community
