Page blacklist, asterix

Hi,

We have “blacklisted” a page where we let visitors sign up for membership (which will give access to the whole site as we have user role subscriber bypassed).

In order for new users to activate their account they receive a mail with an “activate” link which is something like …thesitename.com?uwp_activate=yes&key=xxxxx (we use UsersWP plugin)

Should I manually add blacklist URL for this? …like this?
https://thenameofourwebsite.com?uwp_activate*

The activation link actually seem to work as it is without any manual blacklist url addition, does that make sense?

Thanks!
