I’m gonna be that guy… but former English teacher here - By definition, factoids are inaccurate :) inaccuracies repeated so often that people ‘go with it’, that’s when they become factoids.

‘inaccurate factoid’ is an example of a tautology. Like naan bread, or armed gunman.

If you’re a former English teacher you should be aware that language changes and while “factoid” was originally coined to mean a made up fact, the term is currently mostly used to refer to small inconsequential facts.
