Yes I received the same letter. I did a review on Semalt on my website sharing my opinion which was not very flattering. Their letter said they are going to sue me for damages from 2014 until now.... however I didn't even have my domain purchased until 2015 and the review was obviously written even later than that. I removed my review from my website because I don't want any drama but I ignored their letter. They then sent the same letter to my domain registrar and they emailed me. A legal letter should be very precise but their letter could not even get their dates right. On top of that it says to Sir/ Madam when my full name is clearly shown on my website. I can't take that seriously. They cannot even take the time to write my name?
