I second that concern. Being the maintainer of the FreeType mailing
lists, I face exactly the same problem. Usually, I simply enable
messages in the queue. If I have to do this too often, I tell people
to subscribe.
It seems, however, that the amount of new users is much larger for
LilyPond than for FreeType...

Yes, joining is a *must* in the long run. Only this guarantees spam
protection (not always, but in most cases).
