Albright and Buzzfeed believe that Tumblr has escaped scrutiny so far, and may not be aware of the state of the issue. It's claimed that reports have contacted Tumblr's representatives several times without reply, and also unsuccessfully reached out to Senator Mark Warner for comment. At this point, it's not clear what Tumblr's awareness is, or how it is planning to address the accusations that Russian interference was on the site.

Engadget, which is owned by Oath, which also owns Tumblr via its purchase of Yahoo, has reached out for comment. No response had been received by time of publication, but we will update this story when we are able.
