Account & safety
Content safety
Short codes and destinations we refuse, and why a create might fail with a safety error.
Letlink will not create a link that looks like impersonation, adult/gambling destinations we block, or a short code made of reserved or abusive words. The check runs in the dashboard and in the API/MCP create_link tool.
Short codes
Product paths (login, billing, help, …) are reserved so they can never collide with the app. Separately, a blocklist rejects codes that are slurs, sexual, violent, or classic phishing bait (paypal, secure, verify, …), including hyphenated forms like verify-account.
Destinations
Known adult, gambling, torrent, and disposable-tunnel hosts are refused. Destinations must be http or https URLs we can parse. If you believe a legitimate site is caught by mistake, contact support with the exact URL — do not try to disguise it with a redirector.
After a link is live
We still disable destinations that violate the terms once they are reported or discovered. A previously working short code may start serving an error page. That is intentional.
