Zapping is done at the Editor's discretion and after he himself has evaluated whether it goes against
Site Rules. It would seem that all automated processes for getting answers banned have now been disabled.
Tups,
I am only guessing, but if people named names on your thread, then that would not only break
Site Rules, but would be against the law and make the owners liable for prosecution. In that case, the Ed probably wanted to iradicate all traces of the thread (and any chance of people repeating the offending names) for good.
