Where have the models disappeared from the main page, such as deliberate, chilloutmix? They can't even be found in the user profile

Example

It might be the simplest solution. Maybe you still have some filters on so they don't show up. Otherwise it might be a temporary issue with civit on your side or because of some blacklisted tags you have set.

Check your account settings. I see both after hitting page down twice. Chillout is a special case but Deliberate shows up in the profile as well.
