You can always deactivate your account, from the “Deactivate My Account” link on the Account -> Settings page of the portal.
If you’re leaving because we’re missing a feature you’d like to see, or you think we’re doing something incorrectly, we’re always open to suggestions.
We’re sad to see you go, but if you’re sure, you can delete your account, and we’ll stop checking your hosts for you.
All the history and settings for your account will be permanently lost.
