<html><body><div style="color:#000; background-color:#fff; font-family:times new roman, new york, times, serif;font-size:12pt">Hi,<br><br>I understand that some(could be all) of these are more implementation specific, but was wondering if there is a related guidelines/xep.<br><br>- Should an xmpp server allow a federated user(via Server to server federation) create a chat room on local chat room server? At the least, I see the possibility of attacks where the federated users may create uncontrollable number of chat rooms and even though some policy could be enforced, but what is the normal trend?<br><br>- Suppose the room is created by a local user and he tries to change the affiliation of federated server's user as owner, should that be allowed? What are the possible problems(if any)?<br><br>Thanks,<br>Pravin <br><div><br></div></div></body></html>
