I'm sorry to hear about your experience Quad, hopefully they investigate more and check IPs. Like arctic said hacking it I think is too difficult, most likely you were scammed or tricked in a way that you are not aware of, by a fishing link or a friend. You said you had a few guild members lose things too, maybe there are links being posted in your group chat that are not what they seem. Or it is possible you have been scammed so well you don't realize how.
I'll share a story about how I got scammed so well I just thought the game bugged or something.
I was trading many of the most expensive items in the game to my alt. UPG, Abso set +18, Verdicts Set,Trans Opa Set, Guarder, and a Pet
Something went wrong with the trade, I thought at first I didn't receive because inventory was too full. But then when I checked back on original character the items were not there either. So here I am with no items that I just traded to my alt. When I checked system window from my main it said trade completed. All my **** is gone and that's thousands of dollars.
I was dumbfounded and livid that this game was so buggy that all my items disappear in a trade like that!! or so I thought... I immediately wrote a ticket explaining this. I was really lucky that the GMs helped me out bc when they investigated they notice something in system window that I didn't.
I thought I traded to my alt but really I traded a scammer with the exact same name, but a "0" instead of an "O".
I was tricked so badly I didn't even have a clue I was scammed, and I seriously just thought the trade was bugged or something.
I know you guys think I must be a dumbass to fall for this but, really I am just so used to trading equipment back and forth quickly btwn alts.. and I had 3 windows open on each pc for PA, so I had a lot going on at once and just wasn't paying attention.
anyways I'm really thankful the GMs helped me with my case, and im not trying to rub it in to you I also hope that they will help you, I am only sharing this so people will know my story and maybe can try to avoid scammers like that. Stay safe guys, even if you think your trading with your own alts, take the time and pay attention!!!
So my point is that there are scammers everywhere, don't trust anyone with items or account info, and some of these scammers are using tactics that you might not have even realized up to this point, a lot of them are repeatably banned from many servers here and/or rohan SEA, and pservers. They move from one to the next real quick and have been scamming a long time and thought of all kinds of ways. They make money like this, its possible that this scammer made money from my trade even though in the end I got my items back. If it takes the GMs 2 or 3 days to restore my items, that gave him time to advertise my items for RMT. It's possible he sold some and now even though its returned to me. Whomever bought from him got screwed out of money. This is why these scammers make new accounts after ban and scam over and over, they can make money off of it even if the items get taken from them. They have experience and have perfected the art of scamming. So I guess this can also be a warning that if you come across a RMT offer that is too good to be true, it most likely is!
If the GMs didn't notice that small detail of "0" being an "O" I would be screwed, and I never would have figured it out on my own.
In the end all my items were returned in a few days, sorry to hear its been a long process for you, GL to you Quad.
