I doubt any of these GPTx detection services have a 100% success rate. It's important to be realistic about what they can and can't do. If one were seeking to fool one of these GPTx detection services, it could be as simple as adding a few mispellings or a personal anecdote.
At the moment, defeating the detection is as simple as running the GPT3 output through Quillbot. It's an arms race though.
False positives are a massive problem & 100% successful detection overall is unlikely, agreed.
