Mention flood

Cap how many user or role mentions a single message can contain, and block raw @everyone / @here abuse.

When you'd use it

• Block ping-spam raids ("@user1 @user2 @user3…" copy-pasted lists)
• Stop a single member ping-bombing one channel
• Prevent @everyone abuse from accounts that somehow have the permission

Settings

Setting	What it does
Block @everyone / @here	Catches the literal @everyone or @here in the message body, even if Discord didn't actually ping (e.g. the member doesn't have the permission).
Max user mentions	Maximum unique user mentions per message. Set to 0 to disable this check.
Max role mentions	Maximum unique role mentions per message. Set to 0 to disable.

Tips

• 5 user mentions is a common sane default. Most legitimate messages mention 1–3 people. A message with 8 mentions is almost always either ping-spam or a list of credits — and the latter is rare enough to warrant a log_only first-pass.
• The user-mention count uses the maximum of two signals: regex match of <@id> patterns AND message.mentions.users.size from Discord. So if a member sneaks in <@1234> as plaintext it still counts.
• Role mentions can be more annoying than user mentions — a single @Moderator ping wakes every moderator. Keep this aggressive (1–2 max).
• The everyone/here check looks at the raw text — it fires even if Discord refused to actually send the ping. Useful for "didn't want to ping, did want to fool people into looking."

Common patterns

Use case	Setup
Standard	max_user=5, max_role=2, block_everyone=ON
Strict	max_user=3, max_role=1, block_everyone=ON
Just stop @everyone abuse	max_user=0, max_role=0, block_everyone=ON

Limits

• 6 actions per rule

Behaviour

• The check fires once per message (not per offending mention).
• Exempt roles bypass entirely — useful for @Mod-Alerts style roles that legitimately fan out big mentions.
