Another update to Cloudhiker went live today. Duplicates are now detected way better than before. You might notice that some of the sites you submitted are now marked as duplicates. Many of them were approved by mistake, because they do not match existing websites exactly. For example: a user submitted https://openrailwaymap.org, but later some other users submits https://www.openrailwaymap.org (notice the additional www). Both are the same website, but detecting this was done manually until now. The update changes this. I hope you all understand this strict ruling. Cloudhiker should provide an excellent exploring experience and you should not encounter the same site multiple times.
