What are your views on using automated seo tools, Xrumer, scrapebox, senuke, AMR etc., vs doing the seo manually? What do you feel is more effective? What are the pros and cons of each? Also, is there some kind of discrepancy between whitehat/blackat when it comes to the issue? For example when you're doing blog commenting for backlinks for example with xrumer, that being considered spamming links by some, does that necessarily mean that doing them manually is purely whitehat? Or does it purely depend on how you're making the links regardless of the way you're doing it (tools/manually)? What are you thoughts on this?
