To answer point 3: the chatterbox does not keep a long history by design.
If you want to get a little bit of context on a chatterbox conversion that you missed the start of, use cblast35.

This particular point has been discussed several times in the past.
For starters, see:

• No CB comment is serious, and should not be reproduced in a node without research
• Who owns your words? A resolution is needed.
• Is it a good idea to log the chatterbox?

Cheers.
