OT: mailing list spam protection?

Sorry for a question not about PG but about this mailing list:

It seems that the archives have gone online again, as I now receive
a considerable amount of spam.

A plea to the mailing list maintainers: Is it possible to disguise
the email adresses in the online archives? A simple conversion like
	bla@fasel.com -> bla (at) fasel (dot) com
would probably be sufficient.

Thanks,

Christoph Dalitz
