I found the following number posing as a MyEtherWallet (Ethereum blockchain interface site) support helpline, being indexed by Google using zero search result pages and dumps on medium
Example: https://myetherwallet.ticketleap.com/-18447935953--support-number/ & https://medium.com/@jacobbowen697/18447935953-myetherwallet-support-number-18447935953-myetherwallet-support-number-19b6f677fc76
It's the same kinda deal "What's your problem? Ok, install this remote desktop client and I'lll help you".
The number is 18447935953, which is Michigan based.
