Protect your server without paying for it
Every filter below is free on every server. They are plain rule checks that run on VoidBox's own machines, which is why they cost nothing: no AI tokens, no subscription, no limit on how many messages they check.
See it stop a raid
Run the raid simulator: set your protection, throw a join flood, a slow raid, copy-paste spam or disguised raid messages at it, and watch each account get stopped, live in your browser, using a copy of the bot's real detection code.
What is free
- Anti-raid: spots a flood of joins, locks channels and kicks the raiders (kick, not ban, so anyone caught by mistake can rejoin).
- Word filter: blocked words and patterns, look-alike spellings, sensitivity levels, and an allowed-words list.
- Anti-spam: message-rate limit, maximum lines and maximum emoji per message.
- Anti-invites: deletes Discord invites, with channels and categories where they are allowed.
- Anti-links: deletes links except to websites you trust or in channels you allow.
- Anti-@everyone: deletes @everyone and @here pings and gives a real warning, so your mute, kick and ban limits apply.
- Blocked bots: pick up to 25 bots; VoidBox deletes their messages, kicks or bans them.
- Hacked-account trap: a honeypot channel that removes compromised accounts.
- Anti-scam: blocks over 430,000 known scam and phishing sites and fake giveaway / free Nitro messages, times out the hacked account and DMs its owner. On by default.
- Known threats: blocks bots, webhooks and links already known to be harmful.
- Image scanning: checks posted pictures for nudity on VoidBox's own servers.
What Premium adds
AI moderation (messages judged against your own server rules), profile screening of new members, trust & strikes, and member activity logs that spot a hijacked account behaving unlike itself. The dashboard labels every feature Free or Premium, so nothing is hidden.
You choose what runs
Every filter starts off except anti-scam, which only removes known scams. Switch on what you want in the dashboard's Safety tab, and moderators and exempt roles are left alone.
Questions
What is the best free Discord moderation bot?
VoidBox includes anti-raid, anti-scam links, a word filter, anti-spam, anti-invites, anti-links, anti-@everyone, blocked bots, a hacked-account trap, known-threat blocking and image nudity scanning on its free plan.
Can a Discord bot block links for free?
Yes. VoidBox's free Anti-links filter deletes links except to websites you allow (YouTube, Tenor and Giphy are allowed to start with) and in channels you choose.
How do I stop people pinging @everyone on Discord?
Turn on VoidBox's free Anti @everyone. It deletes the message and warns the sender; you choose which roles and channels are allowed, and admins are never caught.
Does VoidBox moderation use AI tokens?
No. The free filters are rule checks that cost nothing to run. Only AI moderation, a Premium feature, uses the AI.
