I'm trying to join https://lemmy.ca/c/fuckcars@lemmy.ca as a subscriber from my account in lemmy.fmhy.ml.

I've searched !fuckcars@lemmy.ca, that url above, https://lemmy.ca/c/fuckcars, and every variant I can think of - it never comes up in the search as a community I can actually join. I'm not sure what the problem is.

Is it this specific instance/community, is it me?
