This is a copy/paste of my submit to MADBUDA (A hush team crew member) in his Github repo:

Just a question...(I'll wait 24h before spreading the information) IT seems that you own the privates keys of this address : t1Y9ukZMkNAYonCFVp3jSdx7NT8dEsXss7k (or know who own them) It's a famous "watchonly" address created by Hush swing wallet while using BARTERDEX. I sent 20.06795216 HUSH from my Barterdex smartaddress t1VEj5rxQ83NtBLnHqFtzfUKmis43VjQepe on Jan 10, 2018. So I'd like you to give my funds back on my hush address : t1K2XcsKk2gHxT95TLDYauV4SLe8Vps5odu THANK YOU !

So for explanation, the swing hush wallet, when used with Barterdex, create 'watchonly addresses' in wich you can deposit, by mistake your funds.
