I almost posted that same image today. I posted it in the past, on this day. There are probably thousands of people (or more?) who are trying to post that exact image today. They probably have it setup to hide that image automatically. But it’s interesting (and smart) of them to let it appear that it’s been posted on your end without showing it to anyone (it’s like being shadowbanned on Reddit).
But really, was there any doubt that WeChat is being heavily surveilled? It’s the chief reason why WeChat has no chance at gaining real popularity overseas. Other than that small but overwhelmingly important detail, I think that WeChat is the the best mobile chat app that I’ve used.
