There's plenty of DDoS if you're dealing with people petty enough.

The VPS I use will nuke your instance if you run a game server. Not due to resource usage, but because it attracts DDoS like nothing else. Ban a teen for being an asshole and expect your service to be down for a week. And there isn't really Cloudflare for independent game servers. There's Steam Networking but it requires the developer to support it and of course Steam.
