The author was using instance A of Claude to update a `claude.md` while another instance B of Claude was consuming that file. When Claude B did something wrong, the author asked Claude A to update the `claude.md` so that Claude B didn’t make the same mistake again
More likely explanation: Their account was closed for some other reason, but it went into effect as they were trying this. They assumed the last thing they were doing triggered the ban.
I don't understand how having two separate instances of Claude helps here. I can understand using multiple Claude instances to work in parallel but in this case, it seems all this process is linear...
Which shouldn't be bannable imo. Rate throttle is a more reasonable response. But Anthropic didn't reply to the author, so we don't even know if it's the real reason they got banned.
