No, this is and remains anonymous.  Every user should feel comfortable and safe on our platform - this also includes the possibility of blocking other users.

But we always point out that you should never block other users lightly and only for valid reasons. Blocked users can no longer participate in meetings attended by the person they are blocked from and can no longer write to them privately. This is especially annoying if you have been blocked for no apparent reason or recklessly, as you are therefore excluded from meetings.

So think twice about whether you really want to block a person or whether it is possible to clarify the matter and avoid blocking them!
