Single post in Account Breach incident

I feel really bad, I had literally bought a lot of items from this user in form of Z Crystal , Shiny Charms, Melans etc. I should have got my bells ringing when they agreed to sell melans at much less than DP price. I even saw the history of a few melans history and saw that each and everyone was gifted, but it wasn't spontaneous i.e. it was like a month before so I never felt like that. Although it was still not so convincing how they got so many items.. Like I knew that she had atleast 50+ hoard of each and every summon item, it never struck me I hope whoever has lost any items or pokemon due to this user gets it back and they should be given a good lesson for there work. Edit: Also the fact that they went on a very very expensive Raquaza hunt and 2 days before, nobody would have heard there name in past....
