but there's a purpose under the surface

Well, this is unexpected.

Dear oceanplait,

For anyone who doesn't know, that's my name on Tumblr. I'm not directly linking because the link's in the bottom section of the sidebar.

As part of our commitment to transparency, we want you to know that we uncovered and terminated 84 accounts linked to Internet Research Agency or IRA (a group closely tied to the the Russian government) posing as members of the Tumblr community.

The IRA engages in electronic disinformation and propaganda campaigns around the world using phony social media accounts. When we uncovered these accounts, we notified law enforcement, terminated the accounts, and deleted their original posts.

While investigating their activity on Tumblr, we discovered that you either followed one of these accounts linked to the IRA, or liked or reblogged one of their posts:

Near as I can remember, I'm unsure whether I followed any of these accounts (I follow a lot of accounts randomly just to see what they do), but I think I remember reblogging craftykryptonitedelusion, girlsagainst, morningwoodz, and blackprideworldwide. But...now I'm worrying over what I did reblog, and if it was true or false.

You aren’t in trouble, and don’t need to take any action if you don’t want to. We deleted the accounts but decided to leave up any reblog chains so that you can curate your own Tumblr to reflect your own personal views and perspectives.

Democracy requires transparency and an informed electorate and we take our disclosure responsibility very seriously. We’ll be aggressively watching for disinformation campaigns in the future, take the appropriate action, and make sure you know about it.

So I'm a tiny blog on Tumblr, but this seems huge. Tumblr tends to be fairly free-wheeling, even in the post-acquisition days; they block for child pornography, extreme racism, provable hate speech (and the line for what that is slips, now and again)...this seems like a group block purely by association. It also seems to match the patterns we're seeing elsewhere in the attacks on our government, our industries, our voting system...which of course our highest leaders in office deny. So my question is...how big is this thing going to get?
