I think that signature looks great and you should definitely think about running a signature camp.
Is there any one in the forum don't know freebitco? Currently, Freebitco has 29 million users while bitcointalk has 2.7 million users.
In my opinion, not only they don't need to spend money for a signature campaign, they can advertise other platforms on their website and earn money.
Knowing it and currently being aware of it are 2 different concepts.
Have you ever wondered why Coca-Cola is still advertising their business? Do you think they are afraid of losing their market share to Pepsi? Do you think they would be forgotten without the ads?
freebitco.in has a lambo lottery going on but not everybody is aware of that unless they are already visiting the website everyday. Lots of accounts created back in the day but I believe most of those accounts are passive right now.
It was just a suggestion. Maybe they are already making shitton and making a lot more won't really make a difference so they simply don't care probably.
