We used to allow anonymous comments on Philofaxy but the level of snide remarks was increasing so I wrote the one and only contributor/author at the time and suggested they turned off Anonymous comments and considered some form of moderation..

I got a thank you and an invite to become a contributor and to help manage the site... one year on... we don't have any problems on the comments and we have a great community of people contributing comments and guest posts.

You don't need the hassle of the foul mouthed minority. Full support what ever measures you need to take to keep the comments on topic and in sensible shape!

Regards
Steve
