3 of my old email addresses had been terminated 3 months ago.
Then I register a new email on today but this new email account cannot log in
And show me a "contact us" link. So I contact them.
And then they says this maybe because of my IP address.
If there are more than one account created from the same IP address,
Their system will terminate those accounts and blacklist the IP address.
And they suggest me to send them my IP address for further investigating my case.
Should I send them my IP address
