Strong 2nd post (poem), but when you say
Gentlemen's Agreement, where are you getting that? There are specific
Fairplay Guidelines posted by WIS (nothing "loose" about it...other than enforcement). It is helpful to understand that one can engage in "Collusive transactions" alone (a "single user" with 2 or more accounts) or with another. #3 on your list probably should be included in the guidelines, but what the hell does #2 even mean?
CS has stated, it seems to me, that they are not looking for this, but are counting on Collusive transactions to be reported by users. So, report it.
