GuardianGate

GuardianGate is a verification bot for servers that want to control who gets in. New members can be sent through a multi-layer check that may include a CAPTCHA-style challenge, reaction verification, button-based verification, or an optional code step. A verification panel with embedded buttons is posted in a channel, and members work through the steps there before they are let in. Staff can set the verification level to low, medium, high, or extreme, and can whitelist trusted users or roles so they skip the process.

Behind the scenes the bot watches for raids and alt accounts. It looks at account age and how quickly accounts join, and if a mass join is detected it can switch the server into lockdown automatically. Members move between unverified, verified, trusted, and restricted roles as they pass or fail. Failed attempts time out, and a cooldown limits repeated tries so people cannot spam the check.

Staff get a log channel where every verification action is recorded, which helps when reviewing incidents. The bot keeps its own data internally rather than relying on an outside database or paid service. Setup is done by staff: choosing the verification level, placing the panel, and naming the roles and log channel the bot should use.
