Only ppl who may access ur account stole your items lol.. So look towards those who knew your data..
Thats why never give info to anybod, never make same passwords as in other servers, never access 3rd party websites, keypress programs which suspiciously require your login / pw.. Like keypress with auto login haha that was the best so far.
Items never gone alone.. Im having my accounts long years n nothing ever been gone... Cause only one person who knows my data is ME. EH tho... Live n learn... Will be more cautious next time maybe
