Link Detection

Control which URLs can be posted in your server using whitelists and blacklists.

Filtering Modes

Blacklist Mode

All links are allowed except domains you explicitly block. Best for relaxed servers.

Whitelist Mode

All links are blocked except domains you explicitly allow. Best for strict servers.

Add domains (e.g. youtube.com, twitter.com) to your whitelist or blacklist. Subdomains are automatically included unless you specify otherwise.

Setting	Description
Subdomain Matching	When enabled, blocking example.com also blocks sub.example.com.
Redirect Detection	Follows URL shorteners (bit.ly, t.co) to check the final destination.
Embed Suppression	Optionally suppress link embeds for flagged URLs instead of deleting the message.

Redirect detection adds a small delay to link processing. Only enable it if link shortener abuse is a problem in your community.
