A harem ending is planned, which is why the tag was there. It seems to have been removed, because of your report I guess, given the timing. I agree, there was a mistake, I should have specified why the harem tag was there, it's my fault.
About adding the tag when content is not yet present
Let's be clear, I have no intention of changing the rule or anything, but this is probably the only opportunity I have to give my opinion on the subject, so why not. Also, I'm not an experienced user of this site, I frequent it regularly, but I may have missed a feature or nuance. My apologies if this is the case. And if it makes all my reasoning wrong.
From what I can see, a lot of developers use the tag to inform people about what's in it, or not, but also to inform about the type of game they're working on. While I don't doubt that some of them abuse the system to promote the game on content that doesn't exist (and probably never will), I think some of them use it simply because they have no other solution, even if they know they're not clearly respecting the rule.
To take an example, let's say my life deteriorates to the point where I decide to make a netorare game (
), but with very slow progression. If I follow the rule, I won't add the netorare tag until there's real content to justify it. But what does that mean? That most people interested in this kind of game will completely miss out on the first releases, most people don't have the time to check out games one by one after all, and as far as I know, there's no obvious way to search for a game with a future tag system.
As a developer, I can tell you that it's very hard to work several months a day on a game and have it ignored by the community you're working for, and I'm not talking about money here, just the satisfaction of knowing that your work is appreciated.
In my opinion (and this is just my interpretation), the moderators are aware of the infraction some people are doing, but they're willing to look the other way because they're very aware of the problem. If someone is using the tag sytem simply to inform the community of the type of game they're working on, and if this allows the community to have more visibility so that interested people can follow the type of game they want, then it's a win-win situation. There would be no reason to strictly enforce the rule here... unless of course someone pops up and starts making noise.
In fact, I think this rule, and the people who chase developers to have it strictly enforced, do more harm than good to the community. They encourage devs to rush their stories to get content out as quickly as possible, otherwise they won't benefit from the visibility of the tag system. If I decide to do an incest story, I have to rush the incest quickly, even though incest fans would be perfectly fine with an incest story with a slow-burn romance.
In short, there is no perfect solution, and following the rule strictly is sometimes as bad as having no rule at all. At least, that's what I think from what I've seen.
Again, I'm just speaking in general terms. And there's always the possibility that I'm missing some important element. Anyway, the harem tag will no longer be added on this game, I admit it was a mistake because the reason for its appearance wasn't clear enough, which created confusion.
And let's be honest, even if I could convince you, there would probably be five other people jumping on it immediately afterwards. I just wanted to give my opinion on the matter, probably the only opportunity I have to do so....
