There is a cool gig on fiverr where you can get a detailed backlink report (goo.gl/gxD9V). According to this report I have 28 'toxic' links into my site (over 2 URLS) and then around 500 'suspicious' links, some of which have anchor text as 'backlink pyramid xx'. The question is; 'what to do?'. This is because firstly I have heard negative things about using the disavow tool - and it looks as though if you use it you are just helping G look into your site more suspiciously. Secondly, I don't feel like just leaving these bad links linking to my site waiting for them to catch up with me... I have not received anything from G and my results are solid. I am just been careful... Thanks!
