From what I could see with the active campaigns that are more than 100 weeks, they are all casino campaigns, which is more reason why users should respect casinos here, they've stayed during thin and thick times. This is unlike how some so-called reputable users made the whole episode look a while ago when they were intoxicated with m!xers opportunities and others.
It is like a win-win situation for both the forum and the casino because it helps the forum active by incentivizing the quality posters and also they got their brand value established which will definitely bring more positive results in their business. And I am sure some of the campaigns closed not because of lack of business but because they had enough promotion and some ended because they couldn't cope with the competition among new casinos in recent days. It's good to know that I had been part of a few names in the list for long period and it's a privilege to be a part of their journey on bitcointalk.
That is the gist, and technically, we need each other to grow, but my main point is that the casinos and sportsbooks keep the cordiality better than any other sectors, which is commendable. Also, the traffic here is no joke and I believe the companies that value their marketing will always give this forum a try.
As for those campaigns that had left, I believe that it could be for three main reasons; First, it could be due to some financial constraints, second, it could be that their target plan on campaigning on the forum is reached, and third, it could be for their impatience at times.
Some companies need the best results immediately, but it is not automatic. Consistency is the key and I believe it is what the casinos that have been dealing with the forum for long are enjoying over time. It is not all the week they will have some kind of satisfaction, and in some weeks they will be satisfied with the results beyond their expectations. How would those who rushed out know that?
