Random? Who said random? not random.Either malice or incompetence but I really don't care, if you spread FUD you are a troll.
Perhaps the post and the user are only related in that they both spread FUD but otherwise they do look very correlated and hence the guess, feel free to ignore it but I would not be surprised in the least if someone that happily and knowingly does false advertising and spreading FUD on bitcointalk is also capable of doing so on reddit!
Edit: Sorry everyone, i've been feeding the
troll sockpuppet
