I too was hacked from a vanity wallet.  I made two wallets, one for me and one for my 6 year old son.  Both wallets were emptied and the funds sent to the same address on the same day.  Over 1.2 BTC stolen.  I had doubts about the security when I made the wallets.  I should have trusted my instincts.
I have been in the crypto space long enough to know that nothing can be done about this.  If anybody thinks otherwise let me know.
