Are links shown in the Google Search Console (formerly Google Webmaster Tools) "Links to your site" report, dofollow or both dofollow and nofollow?
The links shown in the "Links to your site" report in Google Search Console (formerly Google Webmaster Tools) shows both dofollow and nofollow links (but it's not possible to distinguish between them).

+John Mueller I'm curious why the links that GWT shows include nofollow links. Your thoughts? Does it make sense to note that somehow?
+Yehoshua Coren we show them there because to users, those links can be quite useful regardless. For example, if you have an advertisement on a website, that link - even with a rel=nofollow - can be an important source of users for your website.

Disavowed links are generally treated similarly to nofollow links, and we show those in Webmaster Tools as well (since nofollow links can still be useful to bring traffic to your website).
