Cool idea, but of course the very first image I clicked into was a dick.

I recently learned that in Bhutan, they are sacred smybols since a long time

Since I know that, I am rather amused every time I see a dick painted anywhere.

Haha yeah, can't have nice things I guess. I'm currently working on automated moderation to catch that stuff faster. In the meantime, Report button exists if you stumble into anything awful.

First thing I saw was a Swastika. It was painted on an ex Nazi building, but still...

A swastika or a Hakenkreuz?

Most people do not know about the directional-flip in these signs

The Hakenkreuz is tilted at an angle.

The Hindu and Buddhist symbols are very different.
