Hi Simon,

First, I'm sorry that you (and others) are experiencing spam. On the 
Free-RTC list you wrote:

    I'm operating my own xmpp/jabber server since a few months ago,
    and I have began receiving spam.  This seems like a generic
    problem affecting anyone operating open/federated xmpp/jabber

In fact this problem is quite recent - we had essentially no spam on the 
XMPP network for 15+ years.

I wonder why this has changed recently (aside from the usual story about 
the economics of spam). How are these XMPP addresses being gathered? Are 
they merely being guessed at, or is there something more nefarious going 
on? For example, although this is pure speculation: are there servers on 
the network that are leaking JIDs?
