arXiv:2605.23190v1 Announce Type: new Abstract: Machine-generated texts (MGTs) produced by large language models (LLMs) are increasingly prevalent across various applications, while their potential misuse in fake news propagation and phishing has raised serious concerns, highlighting the need for MGT detection. Existing paragraph-level detection methods commonly treat MGTs as entirely machine-like, overlooking the hidden human-like nature of machine-generated texts: even fully machine-generated texts may contain spans that are highly consistent with human writing. To this end, we first reveal
The proliferation of LLMs and their generated texts necessitates more sophisticated detection methods, especially as their mimicry of human writing improves.
This research highlights the increasing sophistication of machine-generated text, making detection harder and raising concerns about misuse in disinformation campaigns and phishing.
Existing detection methods are now shown to be potentially flawed due to their failure to account for human-like qualities in MGTs, demanding more advanced techniques.

- · Content verification platforms
- · Older MGT detection methods
- · Platforms susceptible to disinformation
- · Individuals vulnerable to phishing
There will be increased investment in developing more nuanced MGT detection technologies.
The arms race between MGT generation and detection will intensify, leading to more sophisticated tools on both sides.
Public trust in online content may further erode as the distinction between human and machine-generated text becomes increasingly blurred.
