Show forum text if foodsaver deleted again

What does this MR do?

feedback from jörg as data privacy officer:

Posts of deleted user:inside may and should still be displayed for the aforementioned reasons. The only requirement is that the name and profile photo of the person should no longer be displayed. Instead of the name there should be something like "Post by user no longer logged in" or just short like currently "logged out user". The actual post, however, should be displayed as long as the post has not been explicitly deleted.

How confident are you it won't break things if deployed?
