Somehow I'd rather have problems with the search bots than with Data protection authority
Seriously: The contact form can be viewed and used even when the board is deactivated, does not comply with the data protection regulation at all and may not be used in the EU area and if so, then it must be noted in the policy, which is then not accessible.
If the board is deactivated, don't forget that you still have an inserted link in your navbar, for example to YouTube or Paypal or any commercial site. Because then the policy must be displayed.
Since it seems to be possible to keep the contact form working when the board is disabled, but not the policy, you have no choice but to continue copying the content of the policy into the contact form.
I do agree that it could be made a little easier to edit. creating a system to be able to edit it from the admin panel would be the ideal thing in my opinion.
That would be the absolute hit. But probably impossible, because then you will only have the policy in the standard board language and not in the other installed languages. Would it?
