If someone is able to insert things into your experience like that, it either has a backdoor or you have FilteringEnabled off. The earlier being more likely. You’d need to patch the backdoor and ensure you don’t introduce another.
You can’t disable/enable FilteringEnabled (FE), it’s enforced.
Are you sure you looked through your game for a backdoor script? Check that all of the plugins you use are from trustworthy creators, let alone the right creators, and that there isn’t a script in the game with a backdoor in it (ctrl+shift+f, find require() or getfenv()).
If you used free models, this might be where a backdoor could be from.
