Of course, Team Wells couldn't have possibly known Ashley Madison was going to be hacked, and that the hackers were going to dump the users' information onto the internet but for the future, a good rule of thumb would be to relegate this sort of stuff to your Hotmail account, just in case. Unless of course you want to discuss the matter with HR, in which case, as you were.
