Search using common foot prints of particular platforms

Example : "Leave a comment", "Post a comment", etc

You can go to Google.com->Blogs and search for the related topic you want and most of all blogs in wordpress and blogger are auto approved.

There is no string to designate which URLs/domains are autoapprove for comments.

Yes there is. You can also find it in forum sites. Most of them came from Scrapebox.

you check some BlogEngine blog website it is autoapprove blog site...

I agree..please elaborate!

All you have to do is to search it manually. And I will tell you that it isn't an easy task.

Thanks for the responses. I wish a few had elaborated. but this gave me food for thought!
