Not exactly. Twitter / X has a mechanism in flagging this with community notes which hints at posts that show such false information even if it spreads or goes viral on the platform. It would be a problem if there was no such mechanism that exists. So I hardly see how this is a problem given such content gets flagged by hundreds of thousands of Twitter / X users.
