Is everything coming from your personal account?
Is this a forum that only allow each people to trade/sell awards from one single personal account?
I definitely have multiple sources, and I believe the other frequent sellers do as well. There is nothing to hide about this, most of people should have noticed that.
I can confirm that the fraudulent activity does happen, and it happed to two of my friends' accounts. What Hyatt usually does is flag the recipient's account for investigation. If you bought a GOH, and your account got flagged, the best way is to reach out the sender and provide the sender's info to Hyatt, they will look into this as Hyatt's detection model is not perfect at this time and always make false positives. Nevertheless, if the awards were actually stolen, your account might be in serious trouble.
From what I know, almost all the flagged accounts are related to the GOH award. I can barely think of a reason why people would want to hack into Hyatt system just to steal their GOH SUA awards to sell, only the dumbest hackers would do that.
Given it did happen, I want to clarify that my awards are legit.

Do you have any other question? list them at one time, it would be hard for people to read and keep track if we keep going back and forth like this.
Don't ask me about the sources of other frequent sellers, I can guarantee nothing but the legitimacy of my own sources. I guess one might have the same source as me, should be legit as well, but I won't tell name because I'm not 100% sure and I can not guarantee for any one else. Also, I'm not saying the rest are not legit, I don't like to do groundless accusations.
I would suggest people to keep track of the received awards, if anything happed, ask Hyatt which award caused the problem, then reach out to the seller, if it's not resolved, report the seller here. For those of you who don't like frequent sellers, just buy from personal accounts.
