This reminds me of the PIK image format (a precursor to JPEG XL) whose name happens to be a word for penis in some languages[0]. In the present case "SPH" is a kink/fetish term meaning "Small Penis Humiliation"[1]. I don't know how many people would think of that, though.
I am not sure if the lesson is to try harder to avoid offence, or live with the fact that words can have multiple meanings and we can be "professional" enough to ignore some of those meanings in some contexts.
