Hey, welcome to the forum.
I just saw your campaign launch a few minutes ago; it's a good promotional move, and I hope to see you around for a long period of time.
I have never noticed anything like that maybe is been a while I visited the service section and if actually they launched any campaign the long lasting depends on the amount they located to the project for the period of the time. Most project only last for 14 days or for a month thereabouts and I don't think such project are really wanting to get the required visibility to enable their project spread across the board also entirely in the forum. Before I forget, welcome to Bitcointalk!
They only last on that span if they didn't prepare a funds intended for marketing and that's one of the reason why some of the business fail. If they could just make their campaign last for long months just like what other did then maybe they can increase up their visibility and maybe will be seen by more gamblers seeking fun in this forum. Anyways we don't know on how long they would last since they are just starting up and if they get good results on their campaign maybe they might think about extending it for more longer times.
But also for OP welcome on this forum and great to see another platform launched here.
