Although I haven't played with it too much, what you need should be
achievable through a feature of many servers, usually called "shared
roster".

Possibly this will not be flexible enough to configure just the
addition of a single contact though. jabberd2 allows you to specify
the default roster for new users I believe. Alternatively a hacky way
would be to subscribe the bot to the messages that many servers
generate on new account registrations, and then it could automatically
send a subscription request.

Just a few ideas, hope something helps.
