This is got to be the creepiest ways to prove your a human. Audio captchas should be the creepiest in my opinion. It would definitely be sounding like a male or female reversed talking sentences, or weird noises of musics while male or female voices saying random letters or numbers… like bro… Anyways, be careful when you come across captchas because you don’t wanna hear these in your nightmares. (Idk why I made this.)
