WTelegramClient ban account

Question

Good afternoon friends; please advise. I used the WTelegramClient library. Did everything as described on the Readme page And right after that, my account was blocked. What have I done wrong?

The code I used

static string Config(string what)
{
    switch (what)
    {
        case "api_id": return "YOUR_API_ID";
        case "api_hash": return "YOUR_API_HASH";
        case "phone_number": return "+12025550156";
        case "verification_code": Console.Write("Code: "); return Console.ReadLine();
        case "first_name": return "John";      // if sign-up is required
        case "last_name": return "Doe";        // if sign-up is required
        case "password": return "secret!";     // if user has enabled 2FA
        default: return null;                  // let WTelegramClient decide the default config
    }
}
...
using var client = new WTelegram.Client(Config);

I need to check if the user is registered in telegram and, if yes, return his ID.

⚠️Reminder: WTelegramClient is an independently developed library for accessing Telegram Client API. We are not affiliated with Telegram Teams and cannot help you with problems with your account.

All we know about Telegram banning accounts is explained in this FAQ.

Sensitive operations on a brand new (VOIP?) account using API calls (instead of official GUI clients) are under scrutiny from Telegram teams to prevent abuse.

You have to make sure to follow Telegram Terms of Service as well as the API Terms of Service.

If you think your phone number was banned from Telegram for the wrong reason, you may try to contact recover@telegram.org, explaining what you were doing.
