As more information has come to light on Russia's alleged campaign to spread disinformation during the 2016 election in the US, we've learned more about how Russia-backed trolls used the most popular websites like Facebook, YouTube and Twitter in their operations.
But what about Reddit, the fourth most popular site in the US?
Reddit CEO Steve Huffman acknowledged Monday that the company has removed hundreds of accounts it suspects are of Russian origin or that linked directly to known sources of propaganda.
"We have found and removed a few hundred accounts, and of course, every account we find expands our search a little more," Huffman wrote in a post on Reddit.
The findings come in response to media reports that Reddit was a source of misinformation during the campaign season and election, won by Donald Trump. In December, researchers led by Rishab Nithyanand of think tank Data & Society released.
The question of whether regular Reddit users unknowingly sharedis harder to answer, Huffman said. Thousands of redditors shared links from @TEN_GOP, a Twitter handle posing as an official account of the Tennessee GOP, he said, and most of those redditors appeared to be Americans "unwittingly promoting Russian propaganda."
Huffman didn't indicate what, if anything, Reddit planned to do to prevent that sort of thing going forward.
"I wish there was a solution as simple as banning all propaganda, but it's not that easy. Between truth and fiction are a thousand shades of grey," Huffman said. "It's up to all of us -- Redditors, citizens, journalists -- to work through these issues."
Huffman added that he hoped revelations of widespread efforts to spread misinformation would prompt Americans to "hold ourselves to higher standards of discourse, and fight back against propaganda, whether foreign or not."
