How to deal with spam comments?

Hi Ashwini, Activate Word Verification under Settings > Posts and Comments

I hope this should solve your problems

The problem is that there is an influx of human spammers. Companies and unknown entities hire such services to promote themselves or save themselves from a bad image. The services of human spammers is also being used to spam in forums. Akismet helps and so does word verification, but to an extent. Usually they use anonymous IP addresses to do such spamming. It reduces most of it, but its best if one deems one as spam manually. Not everyone who share links are spammers.

It depends on your settings... If you want to stop spam, then yes, word verification does help to a certain extent, but that deters some of the proper commenters from giving a comment. Esp. those of us who use mobile to read and comment. 

Can Akismet or Disqus be used on Blogger ? They cut the spam to a great extent

I know that Disqus can be used for sure on Blogger... Its a wonderful commenting platform... Wanted to do the change myself too, but for some reasons, Disqus was not able to sync my existing comments (runnings into thousands of useful ones), and I did not want to loose them... Will keep trying for when they fix the issue, and then will change myself too... Btw, activating word verification is good tool to cut down on spam links, especially when your site/blog has a decent PR... 

If Disqus can be used on blogger then I will suggest Ashwini to use it. It cuts down spam to a great extent. To be double sure, you can get an Akismet API and feed it in Disqus. 

God! I just delete them whenever they come up...anything with obvious spam links. I don't mind bloggers asking me to check out their blogs, but completely unrelated stuff?

But mine is a new blog, and comments are still few. So spam is also less!

Disqus is one of the best tools available to deal with spam comments... Its very much reliable and worthy too

Install disqus, its super amazing! No spam comment what so ever after that!

Spam comments are very annoying.Idelete them manually but as someone said-they are not discouraged at all.

Another fallout which i do not like is,that my page views are not completely of those who come to read my posts;but there is no way of segregating spam page views from genuine ones--or is there?Please tell.

i just optimize those spam comments for my site lol :D

What about a self hosted site on wordpress? Any settings with respect to that?

You can use Akismet.

@Hari - Most of the spammers like posting links. So, go to your comment moderation and ban any comment which contains a link. This will automatically take them to spam folder. If by mistake some useful comment has gone there, you can keep it and delete the rest. 

Remove anonymous commenting from your blog, if you have allowed it. I used to get 100+ everyday and it has stopped since I removed anonymous commenting.

Akismet does a good job, but still few of those which slips in, I delete them straight away...
