As a post-mortem, I never signed that player, and the CV's I quoted were only accepted visits. I ended up somewhere around 30 and gave up. I believe he must have been out of my vision even though he kept visiting. It was a good lesson learned, I think. If you can't cut an AI out after 15 or so CV's, he's not going to sign.
The downside is that it's another example of some really dumb things GD does to keep humans from playing this game. I've had players at higher divisions that tell me up front I'm a joke and they have no interest. Instead, GD let me spend 20k without a return. I ended signing a good class in spite of it, but it just ****** me off.
