CNN tracked down this user but also finds he posted  other material that might get him killed if not force him into hiding if the Left knew about it. 
Using the CNN logo was no crime, it didn't even come close to a trademark infringement. CNN apparently obtained an agreement that unless this user agreed to never use their logo again AND never post other racist, anti-gay, etc. posts, they 'reserved their right to out him.'
The user has right to post anything reddit allowed.
18 U.S. Code § 875(d) Whoever, with intent to extort from any person, firm, association, or corporation, any money or other thing of value, transmits in interstate or foreign commerce any communication containing any threat to injure the property or reputation of the addressee or of another or the reputation of a deceased person or any threat to accuse the addressee or any other person of a crime, shall be fined under this title or imprisoned not more than two years, or both.
CNN should be busted.
