On this forum and others, I see people discussing the ins and outs of blog comments. These discussions range in topic from using Scrapebox to send 1500 auto-approve comments to your website to finding 50 high PR dofollow blogs and leaving 'thoughtful comments' instead. The thoughtful comments are said to be "more valuable than spammy comments". That sounds all well and good, but are 50 'thoughtful' high PR comments really better than 1500 spammy comments? I really would like to know which I should put time and energy into doing. God knows I've put enough energy into research. So which is it? Is SB only good for spamming the hell out of blogs? Can it be used to obtain any quality backlinks whatsoever?
Your honest Scrapebox thoughts are appreciated!
