Cantoner was banned but clearly not all his other related accounts were. (see the list he is on here)
In fact, it could only be a tiny percentage that were banned, as nearly all I have listed (and connected) are still active.
(or was there just lots of zero post accounts banned as mentioned in bbc.spammer thread?)

I wondered, "Was there mass banning of accounts related to Knowhow? (was that based on random individual member reports, or more thorough like here)"
Was it just 1 or 2 accounts involved/banned?
