I use a semi-pseudonymous account for nominal privacy, but it isn’t very secure, both because in practice various well-meaning people (inc me at one point) have mentioned my name alongside it without thinking about it much—which is surely inevitable for anyone who keeps a pseudonym going for long enough—and because anyone with access to the forum’s database could get the email associated with it.

That at least seems easy to fix: register your pseudonym with a new email address that you configure to automatically forward to your main one.
