Any blog owner who wishes to publish a blog, and not be subject to frequent deletion of the blog, as a suspected malware or spam host, needs to understand the responsibilities, and the risks.
There are levels of ability to post comments to a blog, which you select from the dashboard Settings - "Posts and comments" wizard. Protect yourself, if you allow comments.
- Anyone - includes Anonymous Users.
- Everybody with a Google, or an OpenID, account.
- Everybody with a Google account.
- Blog members only.
- Comments disabled.
If you allow comments by "Anyone", prepare to deal with the spam. Note that anonymous users can post either anonymously, or using "Name / URL" tags, at their discretion, with "Anyone" selected. "Name / URL" does not provide authentication. "Anyone" means anyone, period.
Besides "Who can comment?", you may also control comment publishing using CAPTCHA (aka "word verification") screening, and using comment moderation. These settings, like "Who can comment?", are part of the Settings - "Posts and comments" wizard.
Every blog owner, hoping for any visibility in the Blogosphere, needs to choose these settings carefully - or risk being buried by spam.
- Who can comment?
- Comment Moderation.
- Comment Notification Email.
- Show word verification
Comment Moderation, and Comment Notification Email, together, provide 2 settings which can bury your email Inbox, depending upon activity of commenting on your blog. Choose these settings wisely.
