Topic: [e621 Code of Conduct] Official changes, questions and answers

Question: What exactly is considered to be a "common word"?
I imagine that 'flush', 'Canada', 'stag_beetle', 'cherry' etc. are included in this category, but my username for example? And words/symbols like 'aerolite', 'Phaseolus_vulgaris', 'Yucatan_peninsula', 'tanto', '54%', 'Mt._Olympus', 'exuviae', 'hygrometer' etc?
