DDoS protection is pretty vital for a server that is growing and without it, it leaves it vulnerable to attacks like this. I would advise (like everyone else has said) to invest in a different host (if your current host does not offer DDoS protection) or upgrade your current host. I think it's fairly appalling that servers would do this to gain players and destroy communities but it's the internet, we have to learn to understand that the internet still has people who are willing to use things like this to their advantage.
