To create an "Auto-Joiner" for a platform like ROBLOX (which is usually where "brainrot" servers are found), you generally use a Python script utilizing a library like requests or selenium.

Disclaimer: This script is for educational purposes. Automating account actions can violate Terms of Service on most platforms. Use this responsibly.

The Logic
Search API: We use the platform's API to find servers.
Filter: We check if the server is "Brainrot" based on keywords.
Blacklist/Whitelist: A simple list check to skip or prioritize specific servers.
The Python Script
import requests
import time

# --- CONFIGURATION ---
GAME_ID = "1234567890"  # Replace with the Brainrot game ID
BLACKLIST = ["boring_server", "scam_hub", "low_player_count"]
WHITELIST = ["sigma_skibidi_hub", "brainrot_central"]
MIN_PRO_SEC = 10  # Minimum "Pro Level" or metric required

def get_servers():
    url = f"https://games.roblox.com/v1/games/{GAME_ID}/servers/Public?limit=100"
    response = requests.get(url)
    return response.json().get("data", [])

def is_good_server(server):
    # Metric simulation: Checking player count or a specific server name tag
    server_name = server.get("name", "").lower()
    player_count = server.get("playing", 0)

    # 1. Blacklist check
    if any(word in server_name for word in BLACKLIST):
        return False
    
    # 2. Whitelist check (Force accept if in whitelist)
    if any(word in server_name for word in WHITELIST):
        return True

    # 3. Brainrot Quality check (Simulated "10M Pro Sec")
    if player_count < MIN_PRO_SEC:
        return False

    return True

def auto_join():
    print("Scanning for high-tier brainrot...")
    while True:
        servers = get_servers()
        for server in servers:
            if is_good_server(server):
                print(f"Found elite server! Joining: {server.get('id')}")
                # Integration with a browser launcher would go here
                return 
        
        print("No brainrot found. Retrying in 5 seconds...")
        time.sleep(5)

if __name__ == "__main__":
    auto_join()

How to expand this:

The "Pro Per Second" Logic: If the platform doesn't have an API for "Pro Per Second," you must parse the server description. Use BeautifulSoup to scrape the game page if the data is dynamic.

The Auto-Launcher: To actually open the game, you need to trigger the browser protocol:

import os
# For Roblox specifically
os.system(f"start roblox-player:1+launchmode:join+gameinfo:[SERVER_TOKEN]")


The Blacklist/Whitelist System:

Blacklist: Used to avoid "laggy" servers or servers with annoying owners.
Whitelist: Used to find your friends or "OG" brainrot servers that you want to prioritize above all else.
Safety Warnings:
Rate Limiting: Do not send requests to the API faster than once every 2-3 seconds, or your IP will get temporarily banned by the server.
Account Safety: Never put your ROBLOSECURITY cookie or account password directly into a script unless you are running it locally on your own machine.
Anti-Bot: If the game uses a captcha, this script will not be able to bypass it automatically.
