All my Profiles are still visible and active.

Edit, added: There is a somewhat flawed option though on the Profile pages.

At the bottom there are three options: SAVE, CANCEL, and DELETE. On most other sites where you try to delete something, you will get a warning or a "are you sure" popup. The DELETE button on the profile page though, is instant. As soon as you push the button, it's poof, and goodbye for that profile.

I've made the mistake of pushing the wrong button, DELETE instead of SAVE, or CANCEL, and had to recreate the profile I accidentally deleted. So, maybe you made the same mistake?

The team really should change that, so a warning appears when you push the DELETE button.
