If you had trades with a BTC buyer with onion address jsumctnyhgynxmjg.onion:9999 please PM me and send me a screenshot of the trade details as well as the JSON file.
This user is very likely a stolen bank account scammer and we need to gather as much information as possible. Be prepared to receive a chargeback request. If you get one please accept it and get in touch.
Ps: In the new version you can search your trade history for onion addresses.
