I would like to remind everyone that this is a public website and it is unfortunately visited by spambots that collect any piece of personal information that they can find and distribute it to 3rd party advertisers. Private information includes but it is not limited to : Emails, Phone Numbers, Instant messaging IDs.
Having noticed that most referrals to Undernet's Official mail aliases are posted bluntely in the mail@host.com format, I would ask you to discontinue this practice. Instead use an unusual format, such as mail "at" host dot com. This way, we will decrease the number of spam mails going to those mail aliases and will allow the Undernet Staff to concentrate on legitimate requests, rather than filtering out spam.

This of course is valid not only for @undernet.org mails, but it's meant to be as a general guideline.

Thanks!
