Hi, let's say I get a backlink from a web 2.0 subdomain. From my understanding, Google treats a subdomain from a web 2.0 site similarly to a domain. For example, a blog on Tumblr is just a subdomain of Tumblr. I would like to get some backlinks from some web 2.0 subdomains to my money site. What if that web 2.0 subdomain has a lot of bad links pointing to it, even though the main domain itself is highly trusted by Google? (ie. I think Tumblr has a good DA overall and Google sees the overall Tumblr domain as reputable). If there are lot of bad links pointing to a web 2.0 subdomain (even if the domain of this subdomain has a good DA), and then I get a link from the web 2.0 that points to my money site, would the penalty transfer to my money site?
