**Lesson:** When a `urlProbe` needs literal curly braces (GraphQL, JSON in URL, etc.), percent-encode them. This is a general technique for any `data.json` URL field processed by `.format()`.
### 7.15 Rate-limit responses belong in `errors`, not `absenceStrs`
When a site's API returns a rate-limit response, the text may **not** match the `absenceStrs` entry — either because the wording varies between API versions (`"The resource is being rate limited"` vs `"You are being rate limited."`) or because the JSON structure differs entirely. If the rate-limit string is in `absenceStrs` and the actual response uses a different phrasing, **no** absence string matches. With empty `presenseStrs` (presence always true), the result is a false **CLAIMED**.
**Fix:** Move rate-limit strings out of `absenceStrs` and into `errors` (mapping to `"Rate limited"` or similar). The `errors` mechanism produces an **UNKNOWN** result instead of CLAIMED or NOT FOUND, which is the correct semantic: rate limiting means "we don't know", not "user exists" or "user doesn't exist".
```json
{
"absenceStrs": ["{\"taken\":false}"],
"errors": {
"The resource is being rate limited": "Rate limited",
"You are being rate limited": "Rate limited"
}
}
```
**General rule:** Any response that means "I can't answer right now" (rate limit, maintenance page, CAPTCHA, temporary ban) should go into `errors`, never into `absenceStrs` or `presenseStrs`. Only strings that reliably indicate "user does / does not exist" belong in the presence/absence lists.
**Discord example (2026-03-24):** The POST API at `discord.com/api/v9/unique-username/username-attempt-unauthed` returns `{"taken":true}` / `{"taken":false}` normally, but under load returns varying rate-limit messages. Keeping only `{"taken":false}` in `absenceStrs` and all rate-limit variants in `errors` eliminates the transient false positives the Maigret bot was reporting.
### 7.7 The playbook classification works
The decision tree from the documentation accurately describes real-world cases:

| **GraphQL supports GET too** | hashnode GraphQL works via `GET ?query=...` (URL-encoded). You can use either native POST payloads or GET `urlProbe` for GraphQL. |
| **URL-encode braces for template safety** | GraphQL `{...}` conflicts with Maigret's `{username}`. Use `%7B`/`%7D` for literal braces in `urlProbe` — `.format()` ignores percent-encoded chars. |
| **Anti-bot bypass via simple UA** | "Anubis" anti-bot PoW screens (like on Weblate) intercept modern browser UAs via HTTP 307. Hardcoding `"headers": {"User-Agent": "python-requests/2.25.1"}` circumvents the scraper filter and restores default detection logic. |
| **Rate-limit → `errors`, not `absenceStrs`** | Rate-limit wording varies across API versions. If the phrasing doesn't match `absenceStrs` and `presenseStrs` is empty, the result is a false CLAIMED. Put all "can't answer right now" strings (rate limit, CAPTCHA, maintenance) in `errors` so the result is UNKNOWN. |
