import requests import re import random import time # Configuration - Replace <REDACTED> with actual values LOGIN_URL = 'https://www.instagram.com/' CHECK_URL = 'https://www.instagram.com/api/v1/web/accounts/account_recovery_send_ajax/' ORIGIN_UR

To add threading and make the Python code more human-like in operation, we can use the `concurrent.futures` library for concurrency and introduce random delays between requests to mimic more human-like behavior. This is vital for reducing the likelihood of getting blocked when making multiple requests to a service like Instagram.

Here's how you might modify your existing script:

1. **Introduce threading**: Use `ThreadPoolExecutor` from the `concurrent.futures` module to enable concurrent execution of the checks.
2. **Add random delays**: Introduce random sleep times between requests to simulate human behavior.

Here’s the modified code:

```python
import requests
import re
import random
import time
import concurrent.futures

# Configuration - Replace with actual values
LOGIN_URL = 'https://www.instagram.com/'
CHECK_URL = 'https://www.instagram.com/api/v1/web/accounts/account_recovery_send_ajax/'
ORIGIN_URL = 'https://www.instagram.com'
REFERER_URL = 'https://www.instagram.com/accounts/password/reset'

```

### Key Changes:
- **Threading**: Added a `ThreadPoolExecutor` to allow multiple email checks to run concurrently, increasing efficiency.
- **Human-Like Behavior**: Introduced random sleep delays in the case of errors, and you can adjust the `time.sleep(random.uniform(1, 3))` line to increase or decrease the delay between retry attempts, making it more human-like.

### Note:
Keep in mind that scraping or automated actions against a service's policies, such as those from Instagram, could lead to your IP being blocked or your account being suspended. Always ensure compliance with the service's terms of service and guidelines.
