I've always seen the chat used to help generate more users, and give people a chance to make friends and decide whether or not this community is a good fit for them before making any commitments. The past days with random users isn't a negative thing, as remember that you have chat mod rights: if negativity comes up, you have the right and the means to remove them. But if it's just harmless conversation, it could be a fantastic tool to attract people.

I don't recommend adding this rule if you're still encouraging community expansion, and if you intend to advertise on other websites.
