Speculative assumption on my part is that they nabbed the purchaser for repeat transfers not matching names, looked into history of UR > UA transfers from other accounts, and processed shutdowns on those. However, there is also a definite possibility they didn't like the amount of (or lack there of) income the business generated and decided to nix the risk.

As far as the spouse things go, I couldn't tell you where for sure, but I know I've read multiple times of all Chase holders at the same address being shutdown, regardless of last name even. There again, who knows what Chase decides to do, depends if they spill coffee on their shirt and are having a bad day it seems like.
