Signature campaign is good for gaining trust but adding more promotions and rewarding customers is a must since it's what attracts gamblers the most and incentivize them to join new casinos.
Not really we have one casino here with 2 signature campaigns but the community did not trust them, the marketing campaign is very good you are competing for a share of a huge market and you want people to have recall in your brand if Owl.games will offer bonuses, giveaways, and promotions and it is showing in the signature people will be interested to join or take the bonus or participate in their contest.
Signature campaign is just a way to attract new players into the casino. This is a marketing policy of new casinos. And owl.games is a new casino in this forum. Although sig campaign works as legitimacy of an old casino inside this forum.
Currently they aren't offering much bonuses to their users. I can see a 500 USDT weekly wagering contest only. Owl.games is one month old casino and we haven't seen any accusation against them yet. They will gain the trust in the long run if they can continue their journey without any valid accusations here, not by the sig campaign.
Very well put - users on here very much overrate the importance of the forum and especially signature campaigns - yes, it obviously helps for exposure and casinos will get a few signups as well, but it is not the holy grail as some like to think.
