Will keep it short.
(CloudFlare I know you are reading).
First what is CloudFlare? Is CF CDN provider?
- Absolutely NO (free version)! Hardcache of tiny javascripts and css is NOT CDN. If you need CDN BunnyCDN/KeyCDN .
What about CF's DNS services?
- Fast, really fast for "free"
What about CF DDOS protection?
- Good filters
Does CloudFlare protect my privacy?
- Absolutely NO!, there is some "delay of expose" on their Custom paid premium plan tho.
But I'm free CF user what does that mean?
- It mean that CF will spit out your data and their own mother milk to the first complainer with FAKE DMCA complain. (They don't do a basic fact check or source check).
What personal information CF is storing and providing to complainers?
- CF keep your location IPs, your website (hosting) IPs, some basic website stats such as visitors, traffic source. If you are paid user they also have your Payer name and CC info.
Is CF contacting the hosting providers?
- Absolutely NO, they don't have to.
EDIT: Generally speaking there is no CDN provider (Content Delivery Network Provider) who can ignore DMCA due to the complexity of the network distribution.
And NO! I don't hate CF, I strongly recommend them for their DNS services.
