CloudFlare has apparently dropped one of its customers because it runs the Coin Hive crypto mining script on some of its websites. ProxyBunker.online, a CloudFlare customer, revealed that it was informed by the online security, CDN (content delivery network) and DNS provider that it is terminating their relationship as a customer.
ProxyBunker says they tested Coin Hive for a few days and suddenly picked up that their domains deleted from CloudFlare. Further communication revealed that CloudFlare had suspended their services because of using the crypto miner. However, ProxyBunker's Cloudflare services were restored with a warning that should they use Coin Hive again their Cloudflare services will be permanently suspended.
Coin Hive, which officially launched on 1 October 2017 but has been available before that, has been in the news for all the wrong reasons. Two notable cases are that of a South African online publisher, Memeburn, running the script without asking for visitors' permission to use their computers to mine Monero, a cryptocurrency. Another similar case involves Showtime which ran the script on some of its websites but without notifying visitors' that it was, or asking for their permission.
