๐Ÿ“‹ About This Mod

**๐Ÿชถ CapPreventer is the only updated AAE (anti-anti-exploit) <u>free</u> plugin on the market.** CapPreventer tries to block popular anti-exploit mods, so your server can see players' mods without any spoofers. CapPreventer strives to be the top AntiSpoof Pro alternative. If you want to help me achieve that goal, you may report any cool findings for the plugin's development in my Discord DMs. <!-- **๐Ÿณโ€๐ŸŒˆ Happy Pride Month!** --> <hr/> **๐Ÿ” Made for** | Mod(ule) | Operation | Versions | |----------|-----------|----------| | Server Spoof *(optional impl.: (https://github.com/MeteorDevelopment/meteor-client), (https://modrinth.com/mod/opsec))* | **detects / breaksยน** | all | | (https://modrinth.com/project/wdGqOtQ2) | **breaks** | <v1.1.5 (alone), i lost track, new unpatched (requires at least one of some common mods) | ###### ยน Whether it breaks or detects is dependent on the module configuration.
