Comment Verification


So... as unpleasant as it already is for many to comment using Blogger's interface, why do I now require comment verification (even as anonymous comments remain enabled)? Because comment spam is becoming a problem.

Which is weird, because any good spammer should know that blogger has implemented "rel=nofollow" tags for comments, so their spam does them no good in the major search engines. And I doubt that their links are so appealing that they generate natural traffic....

  1. Hmmm, this is a very mild form of verification. "Unpleasant" is certainly not a description that springs to mind.

    This measure would prevent comment spam only if the spammish comments are automated. I guess it didn't occur to me that they were. But if they're automated, why don't popular blogs get thousands of them per posting?

  2. Google has, in my experience, historically done a good job of detecting and automatically deleting automated spam. It seems, however, that a few spammers have found a way around the filters.

    I will grant the possibility that some spammers are posting their spam manually; although word verification can't stop that, it will slow them down.
