Not sure if this is normal behaviour or a bug? It seems like you should not be able to see other user's spam posts when logged in.

• I posted a message that was flagged as spam (yellow box) to a thread that had many replies
  
• I then clicked show postings in top menu
  
• I then clicked the spam message I had just posted which takes me to the thread I had just posted to

The list of complete thread links at the bottom of the page then shows me all the other spam messages that other users have posted to that thread and I can even click on them and look at the spam post??
