I don't know if it's really a part of the SNS culture (as with other stuff listed in teh wiki page) or just a function on some sites to speak much but
I've seen Japanese incorporating it into other stuff

Quoting Mod-san's defense for deletion of a certain other thing being wrong
>If you're referring to the "[REDACTED FOR IRRELEVANCY]" thing that [REDACTED FOR IRRELEVANCY] seems to have a penchant for (regardless of how irrelevant it is to the topic), it's not "tiktok culture" - it was a viral internet phenomenon/meme that hit the mainstream and got remixed to death like all the others in internet history. Since Tiktok is one of the most popular video-hosting sites in the world right now, naturally it was heavily featured there - but it was also all over every other website (well, except this one) and featured on mainstream news. Hell, even Jim "old, out-of-touch man who hates everything new since 1985" Cornette discussed it on his podcast - that's how I first heard about it
>That doesn't mean we should have it all over Heyuri (if for no other reason than because it's old and stale), but it's incorrect to file it under "tiktok culture".
By this logic, it also feels wrong to delete any and all posts that use hashtags
