The email address, in recent years, has become a highly prized piece of currency among spammers (AKA mass-emailers, junk mailers, jerkyheads.)

Because of this, spammers have come up with countless devious ways to gather email addresses from public web pages.

The OLPC Wiki 5,000+ pages are publically available, so please do not post somebody's email address on the wiki unless you're certain they don't mind. This includes using <mailto:> links, which are just as visible as plain text addresses to address-collecting programs.

Want to help clean the site up? Then use some judgement. If you see an email address in the wiki, don't just randomly change it to a form like "foo AT bar DOT com" or "foo@NOSPAMbar.com"; all those silly forms are as obvious to spammers as they are to you. Also, please remember that there are many deliberately published email addresses that should not be changed (such as gnu@toad.com, help@laptop.org, devel@laptop.org, etc).
