It's because Voat uses Cloudflare which is the best (potentially free) DDoS protection that I'm aware of. While Voat should switch off of it, it's not the most trivial thing and it's not like Cloudflare adds no value.
It's unfortunate, but there are remedies for now. If you don't want people to know where you're coming from, use Tor browser, Whonix, Tails, etc.
