A number of IRA and Iranian assets are apparently still live on Facebook, Gab, Telegram, LiveJournal, and other sites - indicating a more expansive operation than has been reported previously. Here's some examples...
(Caveat: just because IRA and Iranian-linked Twitter accounts listed these Facebook pages, Tumblr blogs, etc in their profile, it doesn't necessarily mean those assets were or are still operated by Russian or Iranian intelligence.)
Here's the "Muslim America" Facebook group. One of the IRA-linked Twitter accounts listed this as its profile URL. The group's tag line is "Allies of American Muslims" - the IRA is known to target both pro and anti-Muslim communities online. 
This "news toon" Facebook page was linked from the profile of the one of the accounts Twitter said was operated by Iran.
Another profile referenced smerchenko[.com] - currently down, but archives show was a Russian-language blog web.archive.org/web/2016122615…. The Facebook page has been taken down but it's Tumblr is still live.
Syria is a strong focus of every Russia-linked disinformation network we monitor. Not surprisingly, one of the accounts in Twitter's dataset linked to this Telegram channel, Syria Today.
And of course Gab. One of the accounts suspended by Twitter listed this CovfefeNation Gab profile in their Twitter bio, indicating that the IRA maintained Gab profiles in addition to Twitter, Facebook, Tumblr, and others.
