Remove "Create an account to unlock exclusive content." text from member join form

Squarespace inserts the following text on the member sign up box "Create an account to unlock exclusive content."

This is completely inappropriate for our membership and website. Sounds like an adult content site!

I have contacted Squarespace support and apparently this bizarre text is set in stone?!?

Can anyone help me with this?
