You can comment without spam worries
I received an e-mail today regarding the requirement for an e-mail address and concerns about getting spam as a result. Please let me assure you that your e-mail address is only used for verification purposes. It does not appear on the site, nor can Web crawlers, bots, or other nasties see it and pick it up.
I have left many comments using my e-mail address and have received no spam as a result. I know this because the e-mail address I use here is not the only one I have. I get plenty of spam on the AOL address, but nothing for email@example.com.
So please, feel safe in leaving your comments. No salesman will call. And if anyone else who has commented has had a different experience, please let me know so I can raise you-know-what with the powers that be.
