Anyone can post a title starting with "It is known that X had/did X, therefore what did Y do" etc. The claims in the title can influence anyone reading only the title (majority of Reddit users) without any fact check. This will enhance the spread of misinformation and disowning of the r/AskHistorians subreddit since it is built upon the trustworthiness of the given knowledge.
TLDR: The title claims need to be moderated or banned.
This has been addressed previously in this Rules Roundtable.
