Not going to work for very long or at any scale coming from datacenter/hosting provider IPs. Google "residential proxies for sale" for the tip of an iceberg of how they snowshoe the traffic.
As long as you stick to a single unique IP per account it isn't going to get flagged.
Hey, if the bastards can use residential IPs to suck all information into their models with their crawlers, so can we!
There are lots of botnets providing home IPs.
I use my Codex and Claude Code subs on like 4-6 different servers, ranging from AWS to Vultr to Linode etc.
That’s a major and legitimate use case for developers, Anthropic can’t just block data center/hosting IPs because their actual customers use them on data center/hosting IPs.
