safari-extensions.apple.comは安全ですか？

While I do use Safari extensions, there have been some extensions that are advertised as doing something helpful, but also contain adware in them. Unlike Mozilla (Firefox), that rigorously tests submitted browser extensions for things such as adware, Apple does not, they merely post a caveat at the bottom of the extensions page disavowing any responsibility for the content of extensions. I'm not slamming the whole site, but check out the developers of the extensions before installing.
