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.
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.
- 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.
Nothing runs until you say so
Every filter that can delete a message starts off. 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, 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.
