Here is my take, having run an extremely large social media account:
Being blocked by someone who doesn't like you is a gift in time. In the moment it seems a great insult, a loss, an unresolved human connection you'll never understand why was cut. And you'll let that eat at you for a bit. Sometimes you should reflect on what lead to that negative result.
But again it was a gift. Someone who reacts negatively to your posture on life will henceforth have no further prompts to critique you. To be reminded of your existence and perhaps go into an extended spiel of every reason for for their disdain to all their followers.
The dangerous people don't block you, they revel in surprise of rehashed contempt.
There are people who block me I will never understand and am reminded of on a regular basis trying to view their work. But you come to live with that. It's better to be apart than spark a flame amongst vapors.
