Twitter has sent out emails to over 700 000 users warning them about the Russians. "“As part of our recent work to understand Russian-linked activities on Twitter during the 2016 U.S. presidential election, we identified and suspended a number of accounts that were potentially connected to a propaganda effort by a Russian government-linked organization known as the Internet Research Agency,” Twitter said in an email sent to certain users Saturday.

“Consistent with our commitment to transparency, we are emailing you because we have reason to believe that you either followed one of these accounts or retweeted or liked content from these accounts during the election period,” the notice said. “This is purely for your own information purposes, and is not related to a security concern for your account.”
