You know something useful. You start to share it. Then you read it back. Then again. Then you delete it without posting.
You answer a casual question honestly. The crowd doesn't agree, and the system buries the answer below the noise.
An innocuous comment. Twenty strangers reading it as the worst possible interpretation, in unison.
A real complaint, removed by a bot. You message the moderators. They write back to confirm the bot was right.
You belonged in that room. You disagreed with the moderator once. Now you don't belong anywhere.
Five communities for the topic you love. One dead, one private, one hostile. Your people are scattered.
You went looking for an answer. Every post and every reply was written by a machine talking to itself.
The only community for the thing you love is organized around hating it. Genuine appreciation is the odd one out.
Every thread becomes a joke contest. Try to discuss what actually happened and you sound like the strange one.
