one:

use Recaptcha Extensions. is easy. like my blog comment will be add a Recaptcha for stop spam bot.

some tip for avoid comment spam

• Make sure you set the option to close the comments after a number of days. This is important because spammers will go back to really old posts and comment thinking no one will notice.
• Configure AkismetFilter  Correctly  if you use
• Change  spammer search terms like "Powered by BlogEngine.NET 1.6.1.0" chanege it to "thank for BlogEngine.NET","Add comment" change to say somthing about .." Any of the common phrases you see on the site are going to be targeted by the spam bots.

The results of our efforts
