I have a domain and that domain is mine since 2011.
But when I bought it I noticed that there was a previous owner from the emails I was getting.
I recovered his Google account to leave a message to himself on his "Orkut/Google+", asking him to change his email address from my domain to somewhere else.
Yet as of today, the guy still has accounts under my domains, and a few hours ago he re-re-recovered his Google account (proving he is still active and using that account).
Since I already warned him a few years ago, how can I get rid of this guy since he is getting me tons of spam under my mailboxes?
The easy procedure would be to recover his account's passwords, and delete them. But Google accounts are not anymore that simple to recover. I can't recover it from its own email.
