Ban me at the IP level if you don't like me

We solved a lot of our problems by blocking all Chinese ASNs. Admittedly, not the friendliest solution, but there were so many issues originating from Chinese clients that it was easier to just ban the entire country.

It's not like we can capitalize on commerce in China anyway, so I think it's a fairly pragmatic approach.

Why stop there? Just block all non-US IPs!

If it works for my health insurance company, essentially all streaming services (including not even being able to cancel service from abroad), and many banks, it’ll work for you as well.

Surely bad actors wouldn’t use VPNs or botnets, and your customers never travel abroad?

And across the water, my wife has banned US IP addresses from her online shop once or twice. She runs a small business making products that don't travel well, and would cost a lot to ship to the US. It's a huge country with many people. Answering pointless queries, saying "No, I can't do that" in 50 different ways and eventually dealing with negative reviews from people you've never sold to and possibly even never talked to... Much easier to mass block. I call it network segmentation. She's also blocked all of Asia, Africa, Australia and half of Europe.

The blocks don't stay in place forever, just a few months.

As long as your customer base never travels and needs support, sure, I guess.

The only way of communicating with such companies are chargebacks through my bank (which always at least has a phone number reachable from abroad), so I’d make sure to account for these.
