hereHi @shencoin I guess its not possible to completely guarantee that the photo is yours however if you have a look at the stories on my instagram profile from the 14th December you can see the storm on the night that I took it and hear the shutter clicking in the background. I don't believe you can just assume a photo is stolen however copyright should also be protected so thanks for thinking of it. If you want to help the platform through stopping infringements I suggest having a look at @steemcleaners they are very good at looking after this side of the platform.
