Please restore the S:T. thread
There were lots of interesting and valuable posts in it about small kids learning Chinese.
It is definately OK to delete zhangyanlin's posts (better: his account) as well as those where auntie68 got really, really angry but please keep the rest.
If messages are deleted, I would suggests that all replies directly referring to them should also be deleted, because they otherwise appear stupid. Another possibility: Leave a grey headline "deleted post" at the respective spot. That would also act as a warning to follow-up trolls.
