If you need to change the ETH address then you should submit this form:
Spreadsheet: https://docs.google.com/forms/d/e/1FAIpQLSfGEz_mwhHfNf92YngU5UkPWj9y4-rSAoBvrxrLq1-g4vIHKg/viewform
Example: "Requesting to change the ETH address", after this you get the post link which in my case this post link is: https://bitcointalksearch.org/topic/m.22749133 and you post this in the form
