I think these photographs are yours. When there are rewards involved, people will check to see if what you are posting is really yours.

A 'Search Google for Image' check shows some of these are similar to existing shots, but as you were a likely tourist standing in the same spots I can understand this.

Don't take it personally, the reward pool is valuable and we all scrutinize anything that may not be genuine.

Welcome to HIVE, I hope you like it here.
