To share my own personal opinion:
A thread\'s title or its opening post states its purpose. Once the purpose and need have been met and the thread turns into a meaningless exchange that has nothing to do with the original subject, it\'s time for a small warning. If it continues, it\'s time for a lock.
The thread very much had a meaningless exchange - for example replying to yourself using different accounts is a bad idea, and an obvious method to increase a postcount (again, not stating that this was Zanzibar\'s aim, as it was one of the last things on his mind from what I can tell). Was there seriously a single post useful aside from those involving my replies to Valbrandr and his comments, your larger reply to various previous comments, and one of Drey\'s posts?
If it\'s unnecessary and can be avoided, don\'t post. If there are many accumulating unnecessaries that no longer make sense when referring to the first post, the thread\'s a gonner.
At least that\'s the way I approach things.
*edit*
Houlen Aru, that was unnecessary and close to inviting a flame - thus had to be removed. Maybe I should make one more rule: If you know that posting something will ignite someone in a negative way, don\'t post. Go bite a pillow, go kill some sprites on your computer screen, but don\'t make someone hate you just because you can.
