Not using indexer tools, but what Google expects is a backlink that is truly natural. In my opinion, building my own backlinks by linking sites to other sites through comments, profiles, etc. is not optimal.
Unless, you are using a strategy to build PBN (Private Blog Networks) backlinks. If you do it right like Renovasi Otak, in Google's eyes it will look good and very high quality. Because PBN uses natural blog development strategies and has almost no loopholes. Like the difference in IP address, devices, and so on.
Remember, that is just my opinion.
