AV Video Collection
Open 28g.cc, and you won't see a screen full of flying video previews. Instead, you'll see rows of neat icons and site names. The core logic of this site is 'aggregation'. It brings together all the well-known Asian premium, European uncensored, Chinese subtitled, and even 4K high-definition sites. Whether you're looking for JAV blockbusters or something alternative, you can basically find the corresponding entry here. It's extremely simple to use. Just click on the icon you like and you're in. The most practical feature is that it monitors the availability of links in real-time, so you can see if they work at a glance, saving you the trouble of finding valid domains.
