What does this mean?

[Cornus]

I was reading a thread that I thought was rather interesting, came back to it later and found this for many posts: "Name removed Message auto-removed". It was a new poster [she announced that it was a first post, and by the end of the thread she had 15 posts total]. I was agreeing with much of what she was saying, but most here were not and I guess it got kind of *heated*. I'm just wondering if she deleted the posts herself or was it the admins? I thought the exchanges were very civil [at least on her part] and wonder what happened.

1. The poster was tombstoned. Gone.

2. My magic 8-Ball says she laid an egg in another thread and got a hide

3. Sometimes posters get tombstones if we find out

That they are previously banned people who created a new account and are trying to get back.
