I've been trying to make an account but it keeps giving me an error message whenever I try to create one

What's the error message?|Charles RB II

It keeps saying that 'This action has been automatically identified as harmful' even though I'm just trying to start an official account here. I'm not doing anything wrong, I haven't even made any changes yet, so what's up?

Was this with or without entering an email address to create the account? (If without, try doing it with it in case it accepts that) | Charles RB II
