  "Currently there is no easy way to block all bots using Cloudflare 
   (I can say that after a lot of research and many useless
    chats with their support)."
  "At the moment Cloudflare can only:
    - block malicious bots that perform attacks detected by WAF rules (e.g. SQL injections)
    - block malicious bots that performed attacks or sent spam in the past (based on their IP reputation)
    - block malicious bots that are part of a DDoS attack
    - rate limit bots and users using the rate limiting feature
    - detect and whitelist safe / known bots (cf.client.bot) like Google"
