Every creative and heavy role player would love to see it added, but the newbies on the server don't want it because they aren't creative enough to think something similar, legal and really interesting to "decode" it to the original product.
I like to see creative adverts myself and if I don't need a product, I will try buying it, even if it is just a small amount of it so I can have a chance to see the other player' roleplay and enjoy it together.
But sadly there aren't many people that are in gangs or faction-less which are able to do amazing advertisements and using locations to cover their real dealing product.
