Watchdog is a Discord bot, which runs off of a database filled with baddies. WatchDog keeps these baddies away from all servers which it has access to!
The bans are not synced, so to speak, but if a banned account is joining your server, they will be instantly banned.
*The global bans are made by WatchDog’s Global Moderators, and bans can be appealed on the WatchDog appeal server.
