To find out if a blog is nofollow you can install the 'NoDoFollow' firefox extension. Unless you have installed a plugin for your wordpress blog it will be nofollow by default.
Getting plenty of spam on my blog from this forum - I am seriously not going to approve a 3 word comment with the name set as 'Search Engine Optimisation' am I?
I also followed you with my Google account. It shows up when people click my profile. Right now I have a blog that I have for fun. Write about a bunch of random stuff. I write about 2 blogs a day. Feel free to comment and follow me if you want. Should be PR1 next time Google updates. omgmybffjillwtfjusthappened.blogspot.com
To set blogger as dofollow go to your Layout tab, download a backup of your template, click the box that says expand widgets, do a search in the html for nofollow. Delete that part that says rel='nofollow'
But why not? You know how the big G works, if its a relevant website in the comments linking with nice anchor text its not going to harm your site. It will help it, ok the fact your blog is do follow will not help much but G will match your content with the other blogs content, if that blogger spams his link around with the anchor text S E O (I cant be bothered writing the full name, i guess its been shortened for a reason) his blog is probz gunna have a decent pr and a decent amount of relevant links so its proberly trustworthy to G's eyes. If it was one of my sites and the anchor text was "Hardcore XXX Teenage @$$" then its gunna be bad. Also, if its a 3 word comment, why not add some text you know.. add some more keywords but make it look like a legit link "This site has some great SEO content, I have learnt a lot about SEO.. It helps as i actually own an.. SEO agency myself and we offer SEO to our clients"
