  1. Hey Ravi,

    Akismet is only good for the automated spam bots but it throws a lot of the legitimate commenters in there too. Then you have to literally go through pages upon pages to look for the ones that aren’t spam.

    I hate captcha codes and it’s rare that you’ll find me commenting on a post that has that. The main reason is you have to jump through hoops for them to work. It’s so frustrating when you’ve put the correct code in there and it tells you it’s not right.

    I use CommentLuv Premium and Andy created the Anti Backlink plugin to go with it. I have it set to where unless you have a gravatar you can’t comment. They’ll get a notice telling them until they get that set up they can’t comment on my blog. Even if they do have a gravatar and they are spam, which to be honest with you that hasn’t happened to me yet, I can still blacklist them and email them directly from that comment letting them know why it won’t be approved.

    Since that setting has been in place I haven’t had any spam in over a month now. I’m spoiled rotten.

    1. Hello Adrienne,
      Ya I agree with you that Akismet keep safe from automated spam comments. As you are saying that it includes some genuine comments too in the spam list. It does it only when the visitors use inappropriate e-mails or may be some irrelevant user name. I have encountered with many real comments which were listed in spams but can’t help it.
      Using CommentLuv Premium is really good but you know for beginners it is not possible to afford this premium plugin. So they have to seek for some free plugins. And when it comes to use catcha I have mentioned its disadvantages same as you have. Sometimes people don’t have much time to read and write that captcha stuff and then go for comment. It’s really frustrated. Personally, I don’t recommend that. But for the bloggers who believe that it can be helpful they can go for captcha.

    1. Hey Diana,

      It’s great to use Disqus at any blog. I haven’t use it so can’t say anything about it.
      As you have mentioned about Akismet, it’s a good plugin by if we want to increase the security level then we can use CAPTCHA.

      Thanks for your comment.

      Have a great day a head! 🙂
