I scraped some expired Tumblrs using 'Expired Tumblr Hunter'. 2-3 of them were great, especially 1 which seems to have good metrics, so I registered them instantly. Now how could I check if this domain is spam-free? This is my first time with expired web 2.0 scraping so I'm somewhat sceptical to use them for my money site. All the links are indexed on google and these are the metrics that I found in Moz for one of them. Rest of the referring domains are from Tumblr blogs itself. What else do I need to check to confirm that these are spam-free and safe to use for my money site? Niche is Gaming.
