Guesting vs Disabling

This has probably been answered before. What is Guesting an account and Disabling an account and why is it done?

• Disable your account. It would still be visible but would say "Account disabled" under your handle.
• Guest your account. The admins will only guest an account (replace the handle of the account with "Guestxxxxxx") if there is a serious privacy/security issue.

You must include a reason for either request.

We can't delete your account, your posts, or your reviews. Those are the property of ECCIE.

Thanks - I knew it couldn't be deleted.
