Prefix Gate is a lightweight XenForo 2.3 add-on that displays a configurable interstitial to guests before they can view threads containing a selected thread prefix.
It was originally created for forums that want to place a warning in front of threads marked with an NSFW or similar prefix, but it can be used with any thread prefix.
Features
Important: Prefix Gate is a content-warning interstitial, not an age-verification or access-control system. It is intended to gate normal thread viewing and does not guarantee that every alternate XenForo content endpoint is protected.
Development note: This add-on was made with AI assistance and manually reviewed, tested, and refined on a live XenForo installation. Code review, bug reports, and feedback are welcome.

prevents unacknowledged guests from seeing the first-post content of gated threads through XenForo's stock thread hover previews.
Before a guest has acknowledged the Prefix Gate content notice, hovering a gated thread now displays:
Content preview unavailable until you open this thread and acknowledge the content notice.
After the guest clicks Continue, normal thread previews are restored for the remainder of the configured acknowledgment period.
This applies to both standard XenForo thread prefixes and gated prefixes used with Xon's Multi Prefix.
