Certainly this topic has been addressed, but i do not see (conspicuously, at least) a search field. Hmph.

Regardless. 2 part question.

1. How do i delete, in "one fell swoop" (eg. in one click, as it were), all of the existing spam commentary?
2. How do i prohibit non-registered users from adding commentary (aside from SQL injection, or other means of hacking the system)?

I didn't realize i've so much garbage filling the database.
