Anthropic has been actively cracking down on this exact pattern. They've publicly stated they're "taking appropriate action" against account sharing and reselling, introduced weekly rate limits to combat it, and have been banning accounts that trigger abuse filters.

Their ToS explicitly prohibit reselling. Sellers risk permanent bans, buyers risk losing access overnight. Clever hack, but the runway seems very short.

To protect token holders I've put in a few tricks. Requests only route during the provider's normal active hours, and the whole thing looks like the subscriber just had a busy afternoon. Anthropic sees normal usage patterns from a single account. I've had this running for weeks with no issues.

  I'm expecting some blowback on ToS despite the account protection — I'm all ears. Who wants $$$ and who wants cheap Opus? Form an orderly queue — no seriously,
