Running signature campaigns to help promote their site is just one of many ways to attract gamblers. An alternate method is to run regular contests like Roobet, Duelbits, Crypto-Games etc in the 'Games and Rounds' section.
Wolf.bet should hire someone reputable to manage these contests(Wagering, Deposit, Finding stuff etc). This method has become quite popular in recent times.
TBH & of course just my opinion - it`s indeed one way to attract "gamblers" here on bitcointalk but truth is, as busy as the gambling sections may seem, the amount of actual gamblers is very low. Doing some marketing kind of stuff on bitcointalk every once in a while definitely does make sense but there are much (much much) more important channels in order to really increase volume.
Some people just seem to overestimate the importance of bitcointalk when it comes to player acquisition - I used to do, too.
As someone who got into this gambling business yourself, even if not as casino but a place that reviews them basically, would you say that signature campaigns still do bring people and worth their cost, or would you prefer to spend that money on somewhere else? This is important for both people who do it, and people who are employed by them like us.
I believe it may not be as great as some other options like you said, but I never knew what those options were, I just had some "this is good but there must be something better" but I never really went out and searched for it since I do not own any casino so why would I spend time on that, but now that you are here, and you know these things, maybe you can share that. I still hope wolf.bet does a huge signature campaign, that is always good to get others who play on different casinos, it can't be all zero, I believe that will be worth it.
