Honestly, and I know this from years from experience:

1. "Unspoken Rules" should be spoken at times so people can get it since some people better understand when it's verbalized. Also, as a warning when you take appropriate actions when they break them.

2. THIS IS A BIG ONE! CURATE YOUR DAMN SPACE! I'm not in the mood to be hearing about why certain posts appear on your feed or who I (and others) should follow or block. The moment you log onto Twitter or any site, and you start interacting with things that make you comfortable, you lose all rights to complain. I'm not your damn parent. So learn how to take care of yourself. If you instinctively know how to use a cellphone and the internet, then you should also know how to curate your space to fit your needs.
