> As far as I can tell, the author is French and lives in France. I've heard plenty of stereotypes about the French, but them bit caring about debts if any kind doesn't come to mind.

No, I wasn't implying anything about France; but then, the author wasn't doing the thing that most "people causing problems for hosting providers" do, which goes more like so:

1. register with a stolen credit card that validates at the time, but won't accept payment when the provider goes to collect for the month;

2. rack up billable usage doing some kind of scam; and then

3. when the account gets closed for non-payment, immediately register again, from a new (VPNed) IP, using a new (stolen) identity, with a new (stolen) card.

4. Optionally: do this "in bulk" with multiple accounts at once, perhaps even with scripted automatic bulk account registrations, account "aging" to avoid registration-recency being used as a fraud-score calculation, etc. (You're more likely to see this type of attacker on API services where the service has some kind of per-customer rate-limiting and the attacker doesn't appreciate being rate-limited — they just configure their client software to round-robin their workload across many accounts.)

If you were raised to see this as "using up someone else's resources and depriving others of those resources", then this probably sounds unethical to you, and you will avoid doing it even if it's "easy" to do. But if you weren't, then this probably just looks like an "infinite money glitch" in real life.

If you want me to be concrete about the part of the world where these fraudulent users come from: it's CIS countries. It's hard to tell which people are responsible any more specifically than that — the various CIS countries crop up pretty evenly in attack logs. This is likely because there are many VPN services run in each of these countries, that specifically serve the "other CIS countries" market, and even more specifically serve the "your country is blacklisted from service X? we got you, bro" market.

(I have been witness to posts on scammer forums over the last year or two, that specifically said something to the effect of "full identity kits [IP VPN, identity and matching credit card] for sake! Russian kits on discount because they're unlikely to be accepted pretty much anywhere useful. Ukranian kits marked up with a premium right now, because the west is a big fan of them at the moment, and so is more hesitant to ban them / write rules against them.")

> With the popularity of services like privacy.com where you can create virtual credit cards that will just disappear when you don't want to pay your bills anymore, I think this type of abuse had been calculated into the pricing structure.

There's a simple switch on pretty much every payment processor, that when enabled, rejects cards known to be prepaid/gift cards, only accepting cards that can actually carry a negative balance. Any post-paid usage-based-billing subscription service would have this switch enabled.

A paranoid provider like Hetzner, in addition, probably blocks the Privacy.com partnering card issuer's BIN numbers from being accepted at subscription time. I know our service sure does. (We block the BINs for Venmo and CashApp "cards" too.)
