原文摘录
摘自原文（1383 字符中的一小部分）
When promoting a user to a speaker/host, an offerId is created which can be accepted by the user. However, after accepting them the offerIds don't expire. This means that after the user is demoted back to a listener, they can still use the offerIds to go back to their previous promoted role.
