There is some bot, that keeps building backlinks for one of my site. It points hundreds of backlinks for nonsense pages like shipping, payment etc with its own page title. Looks like the bot somehow got the list from the sitemap. Serp jumps like crazy, search console doesnt show anything, some of the backlink tools are showing them. But after a manual checking the backlinks are all gone. This looks like they wait for google bot, and after a visit they delete the backlink, so there is no point in disavow. Anyone experienced something like that?
