i'm not a broker but i do talk to some OTR .. (off the record) and if folks have no intention of selling (trading/flipping) shares in any co. then yep
pulling their certs can't hurt
imo those certs (if left) are utilized by those whose sole goal is to short against them and *deliberately* never deliver .. it's quite clear that nite has been utilized by those entities whose sole goal is to destroy for profit
