What happens when you buy a kid a new game? Or a puppy?
First few months things go great! All the time, effort, and money is put into it.
After this time the novelty wears off.
Relate this to getting a more expensive, better server.
First few months donations may come in. This will be great.
After a while the server may or may not run smoothly.
If it doesn't, there will be Q.Qing because its a waste of money, and donations will stop.
Someone still has to pay.
And now lets say it does. I can almost guarantee that a few months down the track the "I can't afford it this month, I wont pay but everyone else will" attitude starts.
Perhaps a new game comes out? It only costs $20 on steam, an awesome special. You will play this game more this month, so therefore Disco doesn't need your donation.
One by one, people stop donating. Less money coming in each month.
But, someone will still have to pay to keep the server up.
Who will this fall back on?
Why not start donating now, and we look at this again later. When we can see that the novelty wont wear off.
Anyone thought that something like DDOS protection for our current server, which isn't actually that terrible, would be a better investment?
