Did she really get offended at your tweet? Did she really accuse you of bootlegging? I've been helping Michelle learn twitter for the last week or so and I've been searching out the mentions of her to see what is being said by her fans, so she can connect with them more. Twitter is new to her and she just learning how to reply and retweet her fans.
Could it just have been that she was responding to what she thought was a fan?
I do remember she offered to send someone a copy of an out of print version of Short, Sharp, Shocked (SSS) because someone mentioned they would burn it for a friend since the album is out of stock. However, I had been at Michelle's place the day before and we were going over what merchandise she still had since 2013 is the 25 year anniversary of SSS and we're working on a strategic plan.
