It seems Mr. Anthrax may be forgetting one simple fact: 90 percent of most SA:MP players are minors(underage), and do not have access to money without going through their parents, and most parents do not consider "paying for their kids to spend more time playing video games" to be a worthwhile cause. If SA:MP had a community filled with rich people who have money to blow on gaming, this would be an okay idea, but this is just not the case.
Also, think about this - Argonath has made it clear for YEARS that it accepts donations, and hardly anyone has done so. That is proof that this community of gamers are not able or willing to give money, especially for a very old gaming platform that is very close to seeing its last days. I know that sounds negative, but it's the truth.
