Try to use advance search in finding blogs. site:.com inurl:blog "yourkeyword" include quotations. Hope this helps.
What everyone basically told you above was that your comment got marked as spam when you left it and that you should just skip those blogs, and continue with commenting - on other blogs. I'd recommend you to comment on nofollow-blogs too as Yahoo! and Bing love those links. Good luck!
Make sure you have 3rd Party Cookies enabled. Also try clearing your browser and cache, reload your browser and see what happens. Are you using Firefox ? Have you installed any new (Firefox) extensions? OR try using your open ID to comment...
Basically, you just need to find more spam tolerant/acceptable blogs. It will take some time, but your comments will remain as long as you find the right ones.
Nofollow links are good for Yahoo! and Bing, but since everyone gets lots of traffic from Google - it's great to just optimize for that SE - even though you should optimize for 'em all.
Hello, This kind of problem even I am facing....That when I leave comment and click on submit the result comes out to be blank...I don't come to know that whether my comment is posted or not....
I guess, one reason of this is because of the sites. I also encounter this experience before. Whenever I hit the submit button after I post my comment, a blank page will appear and this incident mostly happen in Wordpress sites that's why since then, I never intend to post my comment on it. Try to search for an effective site that really works. Though I believe Wordpress sites works too, it might just happen due to some maintenance problem.. I guess.
