If people making transphobic comments (which includes continuing to purposely misgender transgender forum users, or being vulgar by creepily obsessing over what someone else’s genitalia might be) honestly don't understand why their reported comments are getting removed by moderators, then I suggest they carefully review the public terms of service, particularly the section that specifically addresses harassment.

These are the official Final Fantasy XIV forums hosted by Square Enix, not some 4chan-like platform where harassers can just repeatedly regurgitate the same regressive, bigoted nonsense (that frequently ignores modern science and basic human decency) and problematic language without expecting to ever face any consequences for that behavior.
