cloudflare has a known habit of taking heavy users and forcibly converting companies from a $250/m plan to a $12,000/month plan.
some people would be happy for that to happen to bad entities like an online casino, but really, to cloudflare the business use is irrelevant and it could happen to any of us.
the lesson is to minimize your cloudflare dependencies. if you have to use it, use it in an agile method where you can move to something else quickly should you need to.
For 12k a month just the DDoS protection would be worth it for a site of that nature and size but they also get CDN access with full control over the caching, and a web application firewall.
The way I see it the casino was trying to plate share at a buffet and got caught so now they are complaining about having to pay the correct amount.
That makes sense, I don't subscribe to !technology@lemmy.world and only ever check ALL if there's an emergency or I'm logging into a fresh install of Sync.
