To be sure, Dworkin is a controversial figure. Though he has appeared as a commentator on TV news programs, his group has been accused of profiting from resistance to Trump by asking for small donations to fund their work, raising large sums, and paying themselves with the money. Dworkin tells Quartz that the accusations are part of a smear campaign.

Funding issues aside, he makes an interesting point about hashtags. Though it’s widely known that Russian trolls have used pro-Trump or anti-Hillary hashtags, and that they have represented themselves on both sides of various issues, like #BlackLivesMatter, to stir division in the US, this appears to be a more subtle effort. Just by pluralizing something, or changing one letter, trolls can dilute a message.

Dworkin says it has happened with his campaigns in the past, and it has been effective. His group of about 24 tech-savvy volunteers who watch for such activity typically see a concerted effort to cause hashtags to morph at about 4am ET, when, he says, it’s easier to create hashtags that will go viral as the day unfolds. On past occasions, he has been certain that state-backed Russian trolls were behind the slightly altered hashtags. This time he isn’t sure.

As of Saturday afternoon, however, the many variations of #TrumpResign were still in play.
