Every website which gets a little bit of traffic or reputation will be hit with massive DDoS attacks. Your option as a webmaster is to use something like Cloudflare, or your content will become unavailable to everyone.

You can block all websites using Cloudflare if you think it sucks.

DDOS mitigation costs are coming down. If you're running a decently sized service and dont have any enemies that want to pay constant rates to shut you down then _should_ be fine. You can even temporarily use cloudflare if you're getting hit particularly hard then remove it when it passes. 100% uptime is a meme and not required for most websites.
