Imagine Cloudflare has all the logs of the IP address that you have ever used to browse your BitcoinTalk account. I do not question that they do not have it yet.
There's other solutions out there, but Cloudflare definitely has the monopoly within the industry. They're unfortunately the best service around in terms of uptime, speed, and features. However, there's definitely been questions about what they do with the data, and who's seeing the data. I've used Cloudflare, and haven't had too many complaints about them. Possibly if there was a decent competitor I'd give them a look though. I think I remember theymos being somewhat reluctant to using them also.
