Actually- This is kind of funny, I reported this exact problem to them (grc.com) on earlier in the week. I got this response on Wednesday, the 6th: ....snip.... It's not out of laziness or lack of concern or attention that we've deliberately chosen not to take any of the measures you've suggested - it's just that we think it's overkill to put everyone through such measures for something that's just not going to be much of a problem. As you probably know, *ANY* and *EVERY* message that's ever sent by this facility will contain a hyper link that takes the recipient directly to their own eMail database page where they can edit and/or delete their membership instantly. ....snip.... We've been literally FLOODED with praise about the simplicity of the system which, we're sure, is due in part to the lack of passwords, hints, clues, confirmations, and the like.

This issue is valuable for plenty of mailing lists, as example take the GRC mailing list : Exemple : http://grc.com/mail.htm (POST) therefor no direct link here. Enter whatever e-mail address and select "delete membership". As for moderation, I thought specific vulnerabilities (i.e intel.com is vulnerable to etc) wouldn't be posted. == Thierry Zoller http://www.sniff-em.com
