Yes. The President of the United States of America and his son both twitted this. Tweeted? I'm neither hip not with the verbage surrounding social media.
They have an extremely large number of followers, so yeah, I'd say it was big. Did the social media policy of removing misinformation from their platform contribute to some of the attention, especially in the minds of those who lean towards the conspiracy theory type? Probably. But you shouldn't let misinformation stand when it's being projected to a major section of the population.
You may be better versed on this than me as you appear to spend more time on the interwebz and are likely more SM savvy, but do either of the Iranian or North Korean accounts:
A) Have enough followers for anyone to care about?
B) Actually release a significant amount of disinformation pertinent to the American populace?
C) Release a significant amount of disinformation regarding COVID?
The one account I could find of actual inciting of violence from the Ayatollah was immediately crushed by Twatter.
Twitter has previously used a newsworthiness standard to defend its refusal to apply abuse and harassment rules to President Donald Trump’s account.
