Oh well... I deactivated my Twitter account. I had already blocked her from any other social media, I just forgot about Twitter because I quit using it...
I seriously wish more LBS's would follow your example! WELL DONE! It's pointless to get into a pissing match over this stuff, so much better to just sever the links. And guess what message you sent to her by doing that- "I DON'T CARE" which is EXACTLY the message you SHOULD be sending.
