I had around 100 spam comments, like
Stefano, two days ago which I had to connect to my SQL Server and delete them all using Query since they were too much and clicking delete, reassuring that I am sure and the clicking continue would have taken me some hours! One solution is as he said, implementing CAPTCHA images, there was an open source project on Code Project for that purpose which can be used, and the other way is just closing comments! But as Stefano has said, if
Scott Watermasysk got the time, it would be good implementing one so we at least don't close our comments.
