Almost all of his links come from Coin Telegraph, so I can only assume he is being paid by them.
Maybe they are paying him, but somehow I doubt they need such type of marketing here. He is wearing a signature, so that's where the motivation for spam might come from. Copy-pasting existing articles, adding maybe a sentence or two, and you are done. On to the next post. It's an easy way to up your post count.
Would it be an option to remove signatures on that board?
That would just cause the spam to spill over to other subs.
At one point in time, we had better moderation in the Bitcoin Discussion board, but I don't think the admins view the Press sub as an important board of this forum anymore to want to do anything to change it. You can get your daily crypto news anywhere you want now. The press board is of minor importance nowadays.
