Hm, ok, true. It doesn't show in the hashtag search on Mastodon :( It does work just fine from PieFed, although there they have a specific field for writing tags. This one doesn't get found with #carryshitolympics (now, this comment, however, should!)
Also, I guess it should work even from Lemmy if the hashtag is in the title because that becomes text in the Mastodon post? Probably?
But whatever. Life is. :)
Still, if anyone is posting such images from PieFed, it would be cool to tag them with that to spread the good word!
