Don't put email addresses or other information you wouldn't want everyone in the world (especially spammers) to have up on this wiki or any other openly accessible place on the internet.
Although this wiki has user registration, it's not a private, access-restricted site. All pages are publicly accessible by unregistered users. Anything you post to this wiki could be read by ANYONE.
We ourselves have no interest in using, selling, or otherwise exploiting data about persons visiting this wiki. But spam-bots and other automated tools of sad little amoralist scumbags do.
Be smart, stay safe.
