It seems like you don’t quite understand how federated services work.

Here’s a quick primer on how you can improve your federated internet experience.

• You can block individual users
  • That will remove posts by them from your feed.
  • All future and historical posts by them will also be removed from your vision.
• If you feel like a community as a whole is allowing behaviour you disagree with you can block that entire community
  • You also have the option of creating your own space with a similar theme, a space that you can police in exactly the way you prefer. ( for example “Video No Politics” )
• In the possible case of disliking the content and/or moderation of an entire instance…you guessed it, you can block that also.
  • Creating your own instance is also a possibility, it can be a bit involved but is certainly possible.
  • Then you have all the control, you can invite your friends, success.

You could also continue to complain about things you can easily fix, that is also an option.

Given your replies so far you seem to be looking for something a bit less echo-chambery (or as i suspect a chamber where the echoes are more to your liking)

Luckily this is entirely possible and relatively easily achievable, have fun.
