Who is the user behind the "Side chain" alt-account? He was the one who was after Sportsbet and LFC_Bitcoin and the allegation being made is that he hacked the account belonging to BitcoinGirl.Club
I agree with you on this.
He created this topic back in July 25th:
https://bitcointalk.org/index.php?topic=5264620that means that he is in contact with anyone that LFC_Bitcoin sent private message
and we have seen unusual rise of accusations against sportsbet, new accounts and protectors.
