moxie, thanks for that additional time reference on the third video. I understand what John Mueller is saying about getting rid of what junk backlinks you can and not leaving them littering the web. That said, while I understand his further caution about not relying on the disavow tool without cleaning up what one can before using it, I've scarcely ever accidently come upon a backlink to a site while searching for the site itself.
As a general principle, it is wise to perform some sort of reputation management when establishing a brand on a newly acquired domain. It sounds like Sgt_Kickaxe has checked the basics. It's worth noting that starting at about 15:11 into the video, JohnMu makes some additional comments putting this discussion in perspective. Overall, if I were Sgt_Kickaxe, I'd be further encouraged by what he says.
Those videos are great stuff, btw. I'll need to find time to view them all. ;)
