Background: I have my own domain and use a different address at each site so I know where the address was compromised. I use wildcard forwarding so I get all email sent to that domain.
I have started getting a bunch of spam to multiple email addresses on my domain and they are being sent to addresses that I have used on other sites, not just random ids. They all have 8888 in the subject line and are a similar format, with a URL pointing to a site in the Philippines. The emails are sent through different servers per Spamcop. It almost seems like some site that manages mailing lists got hacked and addresses got stolen.
Is there anyone who actually investigates spammers anymore, or somewhere to discuss this other than here? I can't be the only one seeing this. I looked on Reddit and was unable to find an appropriate place to discuss so I came back here as a fallback, but even these boards don't seem to be very busy anymore.
