Not really sure what you're talking about here. r/worldnews, r/news, r/UkraineWarVideoReport, r/CombatFootage, r/inthenews, r/RussiaUkraineWar2022, r/Ukraine, r/CrazyFuckingVideos, r/UkrainianConflict, and even r/Damthatsinteresting have posted about it today with thousands of upvotes each.
r/WorldNews even has a stickied megathread about today's news, and sorting by "Hot" on their sub only has a handful of posts not talking about the Wagner Group.
