@jcn-sbwd I hear you. sometimes it’s really hard to find the source! I was checking your links… The first two ones are not accessible. The third one is actually accessible, but my guess that the link already been removed - it seems that MOZ never remove the ones that no longer exist! I have a similar problem with solarpowerpanels.net.au. there are at least 30 high scored spam links that show on MOZ despite them been remove a long time ago!
Maybe try to run your domain on ahref.com - they are much better with backlinks discovery and also they report right away when links are actually been removed. You fourth link tonzo.com is actually got a live link but under a subdomain https://uk.tonzo.com/biz/scambler
