Your suspicions are very justified. There was a player, not naming him specifically who used this method several years ago, though he hasn't been on much in the past year under the names. He was using his BBO name, another male name, and two female names. Notice I'm staying away from identifying him, under his numerous aliases. He was very nervy, even taking on some of USA's star players and of course winning. He came to an end when a sysop, BBO help, was notified , came to the table and booted the ISP number, wherein both the cheater and his alias were booted. And with that one move, BBO became less cheater friendly. So, if you do have the suspicions and see a friendly sysop, ask them to check for you. Some will.... without actually making any accusations. If it's a family game and a husband is simply playing with his wife, it won't embarrass them. If you notice the same "kibber" comes on whenever there's a difficult guess to make on a finesse, then you are right in your suspicions. I've seem that couple on almost daily. I think most are aware of who they are. There are two sets (cheater id and helper id ) that I'm aware of. And of course, there probably are more.
