The com blogger service has an automated filter for spam sent to blog comments. I’ve looked at the records for the first time. Akismet has blocked 271 spam comments since the blog was set up (about 11 weeks ago). I’ve checked the records for the last 15 days (after this period, the spam comments are automatically deleted) and found only one legitimate comment which was treated as spam (which I’ve restored).

So thank you, Askimet – this is a very valuable tool. I guess such tools will be needed for all blogs with well-know APIs and which are open to comments. Note that the sofwtare can be installed on a range of blog applications, and there is a discount for education institutions (although it might be expensive for large numbers of blogs).

I don’t think I’ll have time to check through the records looking for legitimate comments, so I think the responsibility will be on anyone commenting, to ensure the posting gets through the spam filter – and to contact me if the comment doesn’t appear. (Note that if you give an email address, the comment should be posted straight away, whereas if you don’t include an email address, I’ll need to manually approve the submission).
