I have found two issues right now. We really give much time and effort without ant return. Google should address these issues properly.
Qty decreased as well as points due to my Answers and Q&A a lot.
“Window of the World”, a highly reviewed place in Shenzhen, removed from map. I have the photos still under “Unknow Place”. I fear there are other places like this as well.
To get an answer or help on your topic you should change the category of this post to How-tos or Help Desk @Mahbub_LG For many reasons you may lose your points. I have a post on " Points Lost " on the points that I myself lost. Once points are lost they may not return to your account again. If Google removes a place from the map then there is a very potential reason. And before all, pls check your account again to be sure that you did not violate any rules. Thanks a lot for your better understanding. Regards.
I am pretty much sure I have not violated any rule. These are contributed long time ago. And for the same places getting removed, it does not make any sense as the places are really real, popular and reviewed by hundreds and thousands.
Update: I went through your post. So I lost points from Answers due to history issue. 
I have switch Auto Delete Activity to Manual.
Hi @Mahbub_LG
You are posting here about two different subject, that should be managed separately
Probably you missed the point due to an update of the setting for Google’s My Activity . Please read: How do I delete my answers to questions on Google Maps?
If on My Activity your setting is different from this one here below, your answer are automatically deleted and the points not given.
Regarding your second issue, a photo is showing as related to an Unknown place, when the place is “removed” from maps, identified as Fake or never existed. Un fortunately I see a lot of different places identified as Window of the World in Shenzhen, so it is very possible that some of them is a duplicate
@ErmesT Hi, I always check thoroughly before reviewing a place. If there is multiple ones for the same place, then I review only the highest reviewed one. So whoever removed Window of the World, they removed the highest reviewed one then.
