I am guessing that DEF has been asked to stop posting on behalf of IB, because IB is not an advertiser/sponsor on this board. If this is the case, and I repeat, I am only guessing, then any other members who represent their company here, and who do not sponsor this board, should also be considered for banishment. This includes Hitman (for Worldco), Gene Weisman (not sure if he is an advertiser) etc...This is not a personal attack on either of these people, it is just an example. They both positively contribute far more than their fair share.
If this banishment has been caused by the complaints of a sponsor, then it is their loss. IB caters to a lot of newbies who cut their teeth using the low commissions that IB offers. By alienating this audience you may be losing potential clients.
