They're joking, referencing the propensity of companies of late to try and sanitize the internet so people have taken to censoring memes and comments like that, even with words that aren't curse words (thus the existence of words like "unalive" and "sewerslide" to reference suicide.) So much so it has creeped in here from their users and stolen memes as well now.

Though "American?" Iirc TikTok started this mess, and American companies are probably hopping on board now but I don't use anything but lemmy and masto so who knows.
