# Access Eligibility
***
QRbase detected a multi-accounting exploit where players were farming $SCAN by creating new low-level Farcaster accounts to avoid the timer difficulty that comes with leveling up.
### How it works
Every Farcaster account playing QRbase is checked against the **Neynar credibility score**. This score reflects how established and authentic an account is based on on-chain and social signals.
Threshold: 0.5
Accounts with a Neynar credibility score below 0.5 are placed in practice mode. Practice mode allows gameplay but does not award $SCAN or contribute delivered games to Scan Mode campaign progress.
### What this means for players
* Established accounts with normal activity are unaffected.
* Brand-new or low-activity accounts land in practice mode automatically.
* Building up your Farcaster presence (follows, casts, on-chain activity) over time raises your score.
* Practice mode lets new users learn the game without earning rewards until credibility is established.
{% hint style="warning" %}
Creating multiple accounts to bypass leveling is detected and blocked. All farming attempts land in practice mode with no rewards.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.qrbase.xyz/for-players/access-eligibility.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
