- There are a LOT of spam entered in my ring, and I tried deleting one, but it would not delete.
- And, the one I tried to delete is STILL THERE - it did not work.

I had that problem with my ring! Four pages of spam!
Proposed Solution!
When you get logged in, and where you check "View Queue - (RingSurf ADMIN)"
and view the first spam mail, theoretically on the further page of the queue -

when you scan down from the top, past "code check", past "sorting by",
        on a line [delete] [email] boxes in Yellow -
Underneath the line you  can see
     [ ] all members on the page
DON'T check the box!

You "check the box" on the spam mails ONLY.
When you have reached the bottom of the page, move the top of the page and click the [delete]
Two clicks later you land up in Queue, the first page of the queue perhaps, but with spam removed!
you repeat this, so long as Spam lasts!
