As you say Sir and Ma'am, as long as they are paid to do so then they repeatedly do it, and to stop them from ranking up I think that was the sole purpose of the merit system to oppress new members who are just effortlessly typing two words or three word to a certain thread.
But on the other hand, there are also people (let say 2 out of ten), who says "good project", because they believe so that is good because they read info about the project. And not everyone are.judging them to because of this two liner comment, so before reporting them you might as well check their post before this issue...

Well, spamming is a spamming, no matter what your reasons to cover it up. If you really think the project is good, you could say what makes them as a good project, and discuss with other member how others think about the project and what about their expectation of the project. If you like the project and can say it is a great project, i am pretty sure you know about the project, even if it is not too detailed.
