When you create a public group everything will go well for a couple days, at most. Without fail an onslaught of spam will start to come through your group - I've even seen it happen within the first day. It happens to every group and doesn't matter how well you advertise it (or try to hide it). After having watched Google Groups for as long as I have I can only assume that there exists no spam filtering whatsoever. Or, if there is any, it's the most grossly incompetent spam filter I've ever seen.

Le plus gros problème aussi, et que (au moins à une certaine époque), la liste de tous les inscrits avec leur adresses mails était publique... (et une boîte mail de perdue, une). Google, premier récepteur de SPAM, mais aussi premier fournisseur de chair à SPAM.
