Automatic flagging

Sharbull automatically detects if an account is fake or likely to be a selfbot by checking their avatar, creation date, user flags and reports. With this data, a trust score is calculated and further actions may be taken :


Captchas are widely used everywhere and have proven to be effective against selfbots, and Sharbull uses 3 levels of protection :

  • Level One : Users can join your server without having to complete a challenge.
  • Level Two : By looking at the user's flags, Sharbull enables or not the challenge for a suspicious user.
  • Level Three : Everyone including clean users will have to complete a challenge.


An antispam is also included, which automatically flags the user. Depending on their trust score, they may get muted, kicked or even banned.

ALERT mode

When you enable alert mode, any spamming member will be banned without a warning. (Sharbull protection services must be enabled first) Alert mode is automatically enabled when a member reaches the spamming ban treshold. If you want the bot to ignore a channel, block the Read Messages permission of this channel to Sharbull.
