This already happened. A guy got popped for election interference for telling people they could vote for Hillary in 2016 via text or hashtag on Twitter. Frankly, anyone who believed voting via text message or hashtag shouldn't be allowed to vote.
>Douglass Mackey, a 31-year-old social media influencer who operated under the online alias "Ricky Vaughn," was charged with conspiring to spread disinformation designed to "deprive individuals of their constitutional right to vote."
>Prosecutors say the disinformation campaign launched by Mackey and other individuals "often took the form of 'memes.'" Some of the memes altered images of celebrities to falsely suggest they were supporting one candidate over the other.
>While the criminal complaint did not explicitly name the candidates referenced in each meme, Mackey was revealed to be an avid Trump supporter and well-known figure in the "alt-right" movement by The Huffington Post in 2018.
>The group also pushed out the "Draft our Daughters" meme, which falsely claimed Clinton supported making women eligible for the draft.
