I'd need to know what communities/subreddits it was. But many subreddits restrict types of posting that may be seen as hate speech or against the community's limited scope. Posting pro-tankie stuff to socialist communities, anti-abortion stuff to women's communities, anti-lgbt stuff in general, etc, could get you banned. Most of that is probably fine in more general subs but I can't imagine the pro-Andrew Tate stuff would fly in XX, for instance.
