主题已关闭，没有系统记录

@tshenry 如果这有助于调试，在我们的 discourse.group 论坛上这种情况也发生了两次。这是一个神秘关闭的话题（已重新打开）的链接：https://igraph.discourse.group/t/how-should-i-do-for-reducing-graph-object-memory-usage/909

我在 Discourse Meta 上询问了这个问题：

Why do some first posts get locked?

It has happened more than once now on our forum that the first time I see a new post, it is already locked. I am unable to figure out how it might have gotten locked. I am posting here in the hope of getting some tips about what might be happening. Can normal users (not moderators) lock their own posts? The moderation history is empty. If another moderator had locked it (by accident), if would show in the history, right? Does the system auto-lock first posts which appear to be of low quality? …

编辑：似乎当发帖用户尝试删除其帖子时会出现这种情况。已删除的帖子对外部查看者显示为锁定状态，但没有任何迹象表明该帖子实际上已被删除（而不仅仅是锁定）。好消息是，发帖人可以通过“恢复删除”来“解锁”它。有关更多详细信息，请参阅上述链接的话题。
