Note to the community : self promotion is allowed on this community, what we disallowed is excessive self promotion.
Things like multiple post in a short timespan, not disclosing ones link to a specific game, or anything that is made to manipulate the community to make a game look better or more popular that it is really. Sales goes for new account posting ads to games, never to be seen again

So let’s check here:

• He disclosed his link to the game : yes
• Posted about it multiple times is a short time : I didn’t see anything like that, but feel free to report if it is the case
• Is active : yes
• No suspicious link : yes

In my book, this is 100% legit. No need to report.
