My form is disabled

This is the second time my form has been disabled. I am using these services for my GTA V Roleplay crew based on the Xbox One. I would like to understand why this keeps happening?

Hi there,

Apologies for the inconvenience. Your form was flagged by our phishing detector as suspicious as it contains the word "username". However, I manually reviewed your form and it does not seem to violate our terms of use.

I have now reactivated your account. You should be able to access your form again.

Regards.
