I lost $200K+ to a hacked wallet of ethereum-wallet.net . Any way of contacting the owner?

Is there anyway to contact the owner of ethereum-wallet.net ? It was "hacked" and went down in 2018, after doing some research I found this forum where the owner promised to return some of the deposited ETH:

Over the years I sent well over 50 ETH to an address in that wallet. I still have my username, password, and some addresses which belonged to my account, but we had no access to the private keys.

I can still see unmoved ETH in some of my addresses. I'm very devastated and really wish there's a way to contact the owner or access those lost wallets. What happened to them? Do they have any twitter or any social media?
