Blocks a member or a whole role from entering any giveaway in this server. target takes either a member or a role. reason is optional, up to 200 characters, and is only shown to staff, in /giveaway blacklist list and on the dashboard Setup page.
The Giveaways service must be enabled ("The Giveaways service is not enabled here.") and you need the Manage Server permission or to own the server. The giveaway host role is not enough here: "You need the Manage Server permission to manage the giveaway blacklist." Blocking @everyone is refused: "Blocking @everyone would stop every entry. Pick a specific role."
On success the private reply is "🚫 @name can no longer enter giveaways in this server." Blocking the same member or role again keeps them blocked and updates the reason.
From then on a blocked member who presses Enter is told "You are not allowed to enter giveaways in this server.", and one who reacts gets the same by DM after "Giveaway entry rejected:". A blocked role is checked against the member's roles at the moment they try to enter. Bypass roles from the Setup page do not override a block.
Good to know
- Blocking someone does not remove entries they already made in a running giveaway, and the draw does not check the block list. To keep such a member out of a draw, disqualify their entry on the giveaway's dashboard page.
- The same list is managed on the dashboard under Setup, "Blocked from giveaways".
- Undo with /giveaway blacklist remove.
