Yep, classic case of thread bumping, no doubt about that. Since they are also giving a reward to all those that are leaving comments in their announcement thread they are breaking forum rule and usual punishment for that is thread deletion. I reported it too so let's see what mods say about that.
It always make me smile to spot such promotional posts, as they are always positive and has "#" or "$" hashtags. Would a regular forum member use hashtags to write a post? This makes so easy to recognize which post was written with intention to share information or idea, and which one is fake.
This can even be a rule. See post with #<coin/token name> or $<coin/token name> in it - it is 100% fake and was made to get a reward.
