How do I find out who is posting anonymous comments to my blog?These people do not understand the need for anonymous commenting.
You, as a blog owner, have the ability to select the level of authentication, to be required of anybody preparing to post a comment to your blog. For "Who Can Comment?", we find the selection list
- Anyone - includes Anonymous Users
- Registered Users - includes OpenID
- Users with Google Accounts
- Only members of this blog
People who wish to comment anonymously, yet provide a "Name" / "URL" to link back to their Blogger profile, or their blog / website, may do this at their discretion. Anybody doing this provides no guarantee of being genuine, however.
If you allow "anonymous users" to comment, then people who wish to comment anonymously need to be assured that their privacy will be respected. You can gather demographic data about your blogs visitors - and you may infer specific details about individual commenters - but the relevance of that policy will be limited by the precautions exercised by your commenters.
