How do I delete my Spoke profile?
Spoke has an entire page dedicated to getting information removed from their directory:
“All users can suppress their information by clicking on the “Suppression” link located on the bottom of any Spoke Profile page. Clicking this link takes you to a contact form where you submit the URL of the profile you wish to suppress and provide an email associated with that profile so that we can confirm the suppression request. Once confirmed, the page will be suppressed. Users may also request suppression of their information by submitting a suppression request directly to Spoke by clicking here.
