Pyrogram UserBot 检查用户名是否免费

Question

I'm coding with python a telegram UserBot for checking if a username is free . I have a list of usernames in my database. The bot in local works fine but when I up it on Hetzner it has a bug . For checking an username there is a loop that send a request to telegram website.

while True:
    
    vab = "icon_user"
    db = cluster["users"]
    collection = db["list2"]
    results = collection.find()
    for result in results:
        usern = str(result["_id"])           
        url = 'https://t.me/{}'.format(usern[1:])            
        r = requests.get(url)
        if vab in str(r.text) and not "400 Bad Request" in str(r.text):

The if condition sometimes buggy, it returns that the username is free, even if it is busy. I have tried several times to change the variable that the condition checks, but I always have the same error... How can I solve this?

Answer 1

I have found that Telegram sometimes sends the same page to the user as if the username is free when too many requests have been sent. You can try increasing the time between t.me page checks
