In any case, I think you should provide more evidence apart from that one image, or see if someone comes to support what you are saying.
OP has put some random thing here without any valid proof. Don't know where they (localbitcoins) removing the negative comments, but every legit platform tries to resolve the problems whenever someone makes an accusation against them with valid proof. A review platform delete the complain of a user if he/she can't provide the valid proof of it.
Localbitcoins is a P2P buy sell platform (I believe you knows about it as you have used the service before). In that case, user won't be scammed directly by them. The KYC system may bring some complaints. They have launched thei android app just two months ago. Currently, the app have 3.7 ratings on play store. Most of the 1 start rating has been given by those user who faced difficulties while using the app, those are not related to scam. As example:

screenshot 2BTW, app developer/creator can't delete the negative comments from play store, Trustpilot removes the negative feedback if the victims couldn't provide any proof. I don't know how the other review making platform works.
