Q: Will I get my fg back?
A: d2jsp.org doesn't refund forum gold or items. Even though we don't refund forum gold there still is a way that you can get paid back. If the user that scammed you would like to get rid of his locked gold
and scammer tag they are required to repay all scams. This happens quite often and when a user that has scammed you goes through this process you will be informed.
