As a follow-up, this is becoming an issue in the United States too. Of course we know that the porcelain throne isn't designed to support the weight of a human being on the tank and standing on the seat might damage the hinges.

The previous article mentioned national parks. This is becoming one heck of an issue at various national parks. Many of them use "vault/pit" toilets. If anyone stands on the seat and manages to break it, the consequence could include falling in.

But perhaps the most unexpected consequence of the lingual and cultural barriers for Chinese and other Asian visitors who flocked to northwest Wyoming this year played out in the pit toilets around Grand Teton and Yellowstone national parks.
“Our maintenance staff was seeing basically broken toilet seats, especially in the vault toilets,” Teton park spokesman Andrew White said.
In all, about a dozen of the 42 vault toilets in Grand Teton park wound up broken this summer, he said.
What was happening, park officials discovered, is that tourists from Asian countries were squatting, with their feet on the lids, and the shuffling of legs bearing a body’s full weight was causing toilets to snap where the hinges connect the lid to the bowl.
