Reddit relies heavily on community moderation, where unpaid individuals known as Redditors decide what is – and isn’t – allowed to be published on their own corner of the website.
They moderate subreddits, the name given to a forum within the Reddit platform which is effectively a community of people who gather to discuss a particular interest.
Since the controversy erupted, dozens of those subreddits have decided they won’t link to content on X, potentially reducing traffic and engagement.
The biggest subreddits to have enforced the ban include basketball community r/NBA, which has 15 million members, female-focused community r/TwoXChromosomes, which has 14 million members, and American football community r/NFL, which has 12 million members.
It is worth remembering that subreddits are almost always run by fans – it does not mean that the NFL or NBA organisations are taking a stance against Musk.
The BBC has independently verified that at least 100 subreddits have banned X posts.
Of this number, more than 60 have at least 100,000 members.
But the actual number that have instituted the ban will likely be significantly higher by taking into account smaller subreddits with only a few thousand members.
And there are many more communities discussing a potential blacklisting.
