The post must have been flagged as either offensive or spam 5 times. This triggers an automatic lock and delete, as well as an instant loss of 100 rep for the poster. However, I'm not sure why this particular one was removed, nor why TheTXI decided to restore it.

**edit:** for further information on the flagging system, [see the faq][1]
