We ran into the same thing back in the dot-com era. The development group had a sample customer set up as "Master Bait & Tackle", which had an outdoor outfitter theme. With items like fishing reels, lures, backpacks, etc. Entirely innocent (apart from the name).

Sales & Marketing got wind of how consistent the data was in it and wanted a copy they could use in presentations and for trade-show exhibits. We all said absolutely not. But they went around us and got a copy anyway.

It did not go well when a potential customer made a comment about the name during a demo.

Lesson learned. Always use the word "Test" in your test data. Always.
