What Are "Reverse-Proxy Accounts" and "Shared Accounts"?

"ChatGPT Plus carpool, ¥9.9 a month" "Claude membership, shared account, instant delivery" — ten-plus times cheaper than the official price. Sounds sweet. This page does the math behind the sweetness.

One-sentence answer

These services are, at their core, one real account split among dozens of people (via shared logins or technical relaying). It's like sub-renting a single room to a crowd: yes, the rent gets split — but your things may be visible to everyone else, and one person breaking the rules gets the whole house evicted.

Three Very Real Problems
📖

Your chat history isn't just yours

In a shared account, your conversation history may be visible to the other "carpoolers" and the account owner alike. The health questions you asked, the work files you pasted — all in front of strangers. And the fact that you can see theirs too says it all.

⛓️

Bans hit everyone together

Providers explicitly prohibit account sharing and resale, and their safety systems specifically look for signals like "one account logged in from many places at once." If any one of the dozens of users breaks the rules or trips the system, everyone loses access together — and these accounts (many opened with bulk registrations or stolen credit cards) are prime targets for cleanup in the first place.

🔑

The keys to the account are in someone else's hands

The account owner can change the password, read your data, or shut the service down at any moment. ¥9.9 today can become ¥19.9 tomorrow — or the seller simply disappears — and you have no receipt and no recourse, because the deal itself sits outside the official rules.

If you want to save money, there are perfectly legitimate ways: the official Chinese apps (Doubao, Kimi, Qwen (Tongyi), Tencent Yuanbao) offer generous free tiers, with flagship capability in the world's top tier. If you genuinely need overseas models, many legitimate products (like Poe, Perplexity, or domestic platforms that bundle multiple models) offer compliant bundled subscriptions. Add just a little to that ¥9.9 budget, and you can buy the version that doesn't keep you up at night.
