Yes signature campaign is a very good marketing and business strategy because it would help project the name and image of the casino the larger community audience here letting them know that this casino has a better package in stock for them to benefit if they patronise their services.
With a good signature campaign, the campaign must have good referrals. There are many times on this forum where new members have come up to ask which casino that other members of the forum can recommend for them to gamble in, suggestions are always made by members of the forum, and I am sure this suggestions are taken seriously not only by the OP, but by others who read through the thread.
Hunnyplay will be recommended more by members of this forum if there is a good signature campaign running that will bring more exposure to the platform.
