While this problem is well-recognized, existing evaluations predominantly rely on rule-based, synthetic perturbations that ignore the creativity of real users. We organize PCR into a four-way surface-form taxonomy and compile \\ours, a dataset of 500 naturally occurring, phonetically cloaked offensive posts gathered from the RedNote platform.
