5 unusual accounts appeared in this thread and started making unusually formal posts, they all have these weird brief bios on their Profile Page that are written from the third person and seem more appropriate for a journalist on a news site than a user for a meme site, they all appear to be using their oddly generic-sounding real names as usernames (that all have masculine given names as surnames), have strange stock-photo-like portraits for profile pics that seem more fitting for a company ID than for a PFP on a meme site and were all made in the span of a couple hours yesterday. They also all seem to write in the same style and make broadly similar statements. Normally I'd outright call them adbots, but they don't appear to be doing anything but posting their unusually corporate-sounding posts in the GOW:Ragnarok thread.
These are the accounts:
