but linking one wallet that cointains at least 1k XCs to an email address is somehow counter productive in my opinon as we use a privacy centric currency
I understand the concern that verifying ownership of 1000XC may dampen the privacy of one's holdings, but do keep in mind that verifying is entirely optional. This is only required if you wish to have access to the private group for verified XC holders.
Can anyone think of ways that privacy could be maintained while still meeting the requirements for verification?
Maybe one could sign up for an email account with hushmail (using TOR even) just to sign up for Slack. One could send 1000XC to a fresh wallet address (on the TOR stick .ISO maybe) using anon transactions to achieve even greater privacy. Then don't log in to the hushmail account for 3 weeks and it'll disappear into the abyss. You'll still be able to log in to Slack (as long as you remember your login info) and I will have what I need to make sure that whoever is using your username on Slack continues to own 1000XC.
