As far as I know, they haven't run any signature campaign yet, but for sure they could have been receiving some message from campaign managers. And yes, it's the fastest and quickest way to let the community know that there have been a new casinos around.
And they said that they will be active, that is a must in any casinos here. We all know that the bigger casinos started the same, with no views or registrations until they run a campaign and stay longer and then they are very much active. The blue print is already there, new casinos just have to follow it to be successful in this competitive niche.
I do not think that 11Croco Casino has plans of starting any signature campaigns anytime soon. I do not know whether they are unaware of the benefits of the campaigns on this forum or they do not have enough budget to start such a promotion.
However, at the moment they need to fix some things that need urgent attention. Their ANN thread is not attractive at all with only text, they need to enhance their Ann thread and for that they need to buy a copper membership. Secondly they need to be active on this ANN thread and answer every query being made. This is the first step to gain some trust.
