My account was hacked. Please have a look at this
https://bitcointalksearch.org/topic/my-account-got-hacked-1695889I don't understand why didn't you use escrow to trade.
I always demand bitcoin payment to his address 19ZgxTcC1Jn17HwFtqh2rn194WsuMSFjSa from last few years. Dozens of member with whom I traded can confirm my claim. This bitcoin address is verified on my Keybase profile keybase.io/ahmedjadoon
The thing is that the hacker didn't remove/modify Keybase address on my bitcointalk profile. If you had took a moment to check my bitcointalk profile before sending payment, you would have seen that my Keybase.io address was there and so was the "email address recently changed" warning.
To summarize, you did the following blunders:
i) Not using escrow. (I've never discouraged/denied any trader to use escrow while dealing with me).
ii) Not checking my bitcontalk profile properly.
It had an "email address recently changed" warning.
As well as my Keybase.io profile link.
Anyhow, I'm deeply sorry for your loss. I really am upset. I'll see what I can do to make it any better.
