Not being able to find the community - and not wanting to search indefinitely should be a legit reason... and honestly, if I think it's a legit reason to not want to use a zero-support community, then that should be sufficient.

If home education mutes educational posts, then it's not much of a home ed community, in my opinion. If they do that, then I'll leave it to them... and go back to posting in The Terminal instead... or Ladies of Hive... I have other options. It's a pain to have to sort my posts to that degree all the time.
