Hello, i am new to SEO and have been learning alot lately. I have learned that spamming blog comments with scrapebox may not be as effective as manually commenting on high pr niche related blogs. I have been harvesting massive lists of blogs that allow comments and have manually been through about 100 blogs and can't seem to comment on any of them. I have wasted alot of time typing out my comment to make it related to the post and then when i click submit it either says the page cannot be found, gives me a blank white screen, does nothing at all, or just reloads the page and then when i scroll down to see if my comment is there, it is not. I've tried googling the problem but it seems as if nobody else has this problem :S. Did something change in the past few hours? we cannot comment on any blogs any more?
