@LouisIngenthron honestly id imagine if you didnt fold or lawyer up and just ignore such things in most cases nothing would happen. Once it got in front of a judge and you didnt show the judge would quickly recognize there is no case and dismiss it...
Maybe im a bit naive but that is probably how id play it. I mean they cant win a lawsuite at most they **might** win an injunction for me to take down the comment.. Good luck they just spent thousands to remove a comment. Then within 24 hours id have a bot net going with 100,000 comments of spam :)
