Example incident. Frostpeak and @mod_kai are made up to show how Sleet is built to respond.
Every destructive action a staff account takes counts toward a limit you set. Cross it, and Sleet quarantines that account, admins included.
Discord's role order still applies. Sleet can only act on accounts whose top role sits below its own, and it tells you when it can't.

Roles
4 roles removed by Sleet at 03:12:08
A trusted account, often a hacked one, starts deleting channels, banning members or rewriting roles.
Sleet's anti-nuke protection is built to count destructive actions per account and quarantine any account that crosses your limit.
In development
Hundreds of fresh accounts join within minutes and flood every channel at once.
Sleet is built to spot join waves, hold brand-new accounts at the gate, and lock joins while staff respond.
In development

Sleet is built to catch scam links in messages and remove them before anyone clicks.

Every protection Sleet ships during early access is free. Premium comes later, and you'll hear about it before anything changes.
See pricing plansQuarantine and lockdown change roles and channel permissions across the whole server. With narrower permissions, Discord's role order blocks those actions in ways that are hard to spot until an attack. Sleet still can't act on anyone whose top role sits above its own.
No. Each server's settings and incidents belong to that server. Sleet doesn't build profiles of people across communities.
