I noted that the plusnet server had killed them before I saw them,
however there was an interesting side effect, in that the original
"mice" thread headers were also removed from the server as well. I only
noticed when I synched another copy of Mozilla on another PC that the
whole thread had vanished, yet I can still access the original messages
from my cached thread headers on this PC.


That's because the original messages have been superceded by the fake
ones - Hipcrime NewsAgent allows the user to issue supercede or
cancel messages by impersonating the original user.
