@OddHouseGames – From what I understand, subbing to hashtags only works on posts within (or that have been pulled into) your instance. This is an issue that exists on the fedi, regardless of the service you use. The instance you use, will only pull in posts from outside your instance, if you (or other users on your instance) follow them directly. Hashtag following will mostly only work if you have a lot of people on your instance who follow users on outside instances, where those posts are pulled into your instance, and searcheable by hashtag. At least this is how it used to function, I cant speak to the validity of this state ment in the current ecosystem. This is/was in an attempt to keep resource use low, so anyone could run a server, without hosting the hundreds of thousands of posts from all of the federated servers. It would be unviable for a single person to host; monitor; moderate and server all of the posts across every single server. The bandwidth alone would be immense. The thing to remember is that not every post in the fedi resides on every server. I’m open to being corrected of course, this is/was just my understanding of the situation.
