Hi rmeeuwsen, I was kind bored yesterday and knowing you have a few sites I got curious. I did a few checks to see if any of your other sites were hacked, and if any share the same servers.
Your site infoarea.com has also been hacked. But, not by the same hacker it seems.
Kinda strange cause this TLD is not listed in your sites at the GPWA. But infoarea.com is used as your contact email info for lucky-777-casino.com, which hasn’t been hacked.
Just a thought, but have you pissed someone off recently?
