Once you go no-follow… you’re doomed
I know lots of people talk on and on about spreading link love in the blogosphere and removing no-follow from your comments so you can appreciate your readers and reward them with a good quality link.
This sounds very nice, but… In the early days of this blog i used a do-follow plugin in order to attract more comments. After a couple of months, manual spam comments reached such a level that i came back to the all so good "nofollow". But… the damage was already done.
As i found out later, my link was included on a couple of do-follow blogs lists. And this sucked. As these lists spread like plague and spammers use them for "link building". Thus, every day for the last year i received at least a couple of such spam comment. How can i tell? Well… because these comments don’t have a real person’s name in the Name field, but a Keyword.
Now, what happens to these comments? 95% of them get deleted instantly, but i still approve some of those that really make sense. They still remain a pain in the but though.
So, as a bottom line, i advice you not to use do-follow on your blogs. It’s not like it would get you so many thanks from your readers if you do, but it will definitely get you a lot of spam. So, better not

I use the commentluv plugin and have no-follow disabled from the comments area.The akismet plugin takes care of the spam and the “math-problem” spam catcher helps a lot as well.I manually approve all comments.
I manually approve them too…
As for Akismet, the kind of spam comments I’m talking about can’t be stopped by it, as they are made manually and not by bots.
I also manually approve comments.

I don’t like nofollow blogs. If blog is nofollow our baclink is not important. Because of this I like dofollow blogs
