Sorry to hear this, one of my friend @eldaniel0131 got compromised as well.
The scam started when he tried to login on a fake @splinterlands phishing website that he search on google search.
Sad that you lost money on this but the best advice I can give I guess is to change all your passwords immediately
I'm already done to all of the needed measures to secure my account. Its a harsh lesson to me, i guess.
