Well, whatever we build is archive-able at anytime, so it&#x27;s hard to technically disallow backup of data if Eve is bent on spidering all of the data.<p>Instead how about no contact-data (email&#x2F;phone) be made publically available  at all. And all friends request, messages or recruiter contacts goto a public box for that contact? So we can recycle old PO boxes after set intervals, and you only listen to the latest one. Anyone trying to reach you has to be OKed by you.<p>There&#x27;s also another negative PO, and you try to keep that empty. Bad player that spam you get a a megative PO message, and those that get too many such are lowered on some scale.<p>Or of course, charge per action, so it&#x27;ll be cheaper for someone to contact a dozen people, but too expensive to mass spam.
