You do realize that some Developers simply don't know the meaning of harem, don't you? So, how about being understanding a bit?
Also, even when it comes to definition, due to website's definition, harem - is having 3+ girls, but it seems you guys consider harem as having all the females in a game. Technically the game still can have harem tag, it was deleted in order to not to deceive people like you.
Nobody would mock you or snap at you if you simply just let it go and like you said - "focused on other games that are worthwhile ", but no, you, guys, just keep at it - "where is harem?", "we want harem", "you promised harem"... sure people get annoyed, what do you expect? Do you really expect the Dev to change his plot and story? to change his characters personalities? so you could have them all? That's not gonna happen.
