hacked skype and sythe account

Hello, this morning I wake up and logged into skype and there were several messages who have been sent during the night regarding buying 07 rs gold and someone actually got scammed. These messages were not sent by me and my sythe account was hacked too, someone sent private messages and opened a thread for ikov buying. I don't know how to prove it but some of my contacts realised it wasn't me. I don't know what to do, I'm freaking out, I even got a scam report now, please any moderator help me!
what do I do next? Is there like an IP check possible or how can I prove it?
thanks for your time

 

Even if you proved that you were hacked, you would still have to pay back the users who got scammed since you lost control of your sythe account. Failure of reimbursement will lead to a perm ban. Prime example as to why 2 factor is a must have and blessing.

 

As Ghast said, you're held liable to keep it short.
