This is exactly like Reddit. On Reddit, if you subscribed to “gaming”, you would not also see posts from “games.” You would have to subscribe to both to see posts from both. If you want to see posts from [email protected], but also from music communities on other instances, you would subscribe to both.
They don’t technically have the same name. The full name will be something like “[email protected]” or “[email protected]”. The problem is whatever interface op is using isn’t showing the full community name which includes which instance it’s on.
The hashtags are also kinda useless in another way. For example, if you follow the hashtag “#music,” (or any music-related hashtag, really) your feed will be filled with bots that just post YouTube links. You can go through and block these accounts as you see them, but there’s so few people using the hashtag in a non-spammy way that you might as well just not follow the hashtag in the first place.
Without any actual wrestlers or wrestling journalists on mastodon (which I am neither), there’s not much that could be done to build a community. Plus, I don’t have the time or energy to moderate a community. Plus, posting stuff “from Reddit” kinda violates the whole point of, you know, not using Reddit.
If I understand correctly (and I probably don’t,) there is a fix but it hasn’t been implemented yet.
