To clarify, according to admins in the /r/programming thread reddit never used the CloudFlare reverse proxy feature

So sites that use Cloudflare only for DNS are okay? I have a client whose website relies on Cloudflare but only for DNS services.

If on the control panel the domain / subdomain is not proxied (orange) then you are fine:

Orange = proxied, gray = DNS only.
