Yes, I don't think we need to discuss the campaign further, it started when Lightlord announced when the payment was low LL addressed it and increased it to a considerable amount so those who wish to join then it's their choice, and if someone feels they are spamming then use the report to moderator button and @CryptopreneurBrainboss is capable of identifying them as well cause he managed both bitvest and 777 at the same time in the past.
Now let the ANN thread serve its actual purpose and if you still want to discuss further then I suggest you create a separate thread somewhere appropriate.
What's the ANN's actual purpose in your opinion?
There is absolutely nothing wrong in discussing the signature campaign (or any other marketing actions) in this thread. That's what ANN threads are for - discussing anything related to the business. The signature campaign thread is meant for the manager and participants (and is self-moderated) and not for general discussion. And the idea that we should be starting a separate topic for each type of discussion relating to Bitvest is, softly saying, bizarre.
And I don't think LL minds having his thread boosted up to the top of the Gambling board.
In general you are absolutely correct that ANN thread is to discuss anything related to the business, there is also no specific rule that we are not allowed to talk about it but it is just rare to see ANN thread is being used to discuss about the payrate of the signature campaign too much/further. At least I do not see people talk about the payrate of the signature campaign in other ANN threads. In my point view, ANN thread is better to be used to discuss more about internal things that we can find on the casino's site, such as promotion, games, deposit/withdrawal etc.
