I think things are a bit more complicate, @Kia_Faraji
You know me, and you know that, like you, I am a volunteer, so I am not speaking on behalf of Google.
And you also know that I am used to go straight to the point.
The issues that you are finding are not happening only in your Country. I am reporting and merging duplicates, or at least trying to, several times every month. And I spend a long time in this community, reading a lot of posts where the Local Guides, depending of the situation, are complaining for the reason “A” or for the opposite of “A”.
I was fighting against a Local Guide who was adding Fire Hydrants, categorizing them as Hospitals. I was fighting with Local Guides that were adding speed control as Police office
The community complain because too many edits are approved (spam) and because many edits are not approved (too many restrictions). So where is the point of balance between “open” and “too restrictive”? I personally don’t have an answer.
In my life I am designing control systems for large automated plant that are processing vegetables, and I have to fight every day with similar issues: People who wants less restrictions (algorithms) in controlling the machines, but that is coming to me every time they do something wrong “because the algorithm should block me if I am doing something wrong”. I am talking about plants with 1000 workers, so I can clearly imagine how difficult can be to apply this to a larger scale. We are talking about more than 150 millions Local Guides and this means more of less 3 times the whole population of my country, or two times the population of yours.
It means that you cannot have a person to check all the edits, all the reviews, all the photos that are added every single day of the year. So, you must have a software (call it algorithm, or AI, if you like) to check and verify the contributions.
How should this algorithm be improved, in your opinion? Making the edit easy (more approval) for you to be able to merge or remove the duplicate, or making the edit more difficult, to avoid someone to add a duplicate, so that you dont have to remove it?
I don’t have an answer, but I have an opinion: choose the compromise that give you less fake locations.
But, if you have a better idea to suggest, we can talk about that, but first of all I think we need to know the size of what we are talking about.
Then, if you want to share a link and show the procedure that you used to attempt the merging, I know that many Local Guides will be happy to share their experience with you about the way they use to merge two or more places. What I personally do is to monitor daily Maps in my area, to fix and remove the issues quickly, because I think that nobody should be in the condition of the lady mentioned in your post.
And yes, I am sorry for that lady, like I am sorry for someone who have an appointment for a job, and reach the wrong location, and for everyone who have an issue due to bad information added by a Local Guide.
Don’t get me wrong, I know that the fact was very emotional and I can understand that you are “on fire” for this. It would be the same for me. But we need to be rational, if we want to fix something and to improve it. This is the important point, not the numbers. Again, I agree with you
