Hi,<br><br>there could be other reasons to block subscriptions. Maybe the operator of the service decides that Alice and Bob are on different realms, and are thus not allowed to subscribe each others status. Explicitly blocking these requests, eventually with a reason would be the right way to do this.<br>

</div>But then Alice will know (or can know) that you have rejected her!<br>

Imagine you want to "captivate" Carol but don't want Alice to know that you<br>
are connected. You don't want to reject Alice, but just set "invisible" for<br>
her (you don't want to reject Alice because if you don't captivate Carol you<br>
would like to try with Alice later). :)<br>
