I think the OP of that post would have had a better reception if they had:

• Responsibly disclosed what they found, rather than using it to stir up drama on social media.
• Mentioned that it's just a web forum account, not connected to game accounts or anything else of value.
• Targeted the software vendor (https://www.ubbcentral.com/) instead of picking on one particular customer who used that software.
• Refrained from spreading misconceptions and unfounded assumptions about how the technology works.
• Responded to the reasonable follow-up questions, such as those that came when readers discovered that the problem was reported fixed three years ago.

People in that thread responded with skepticism and criticism to an irresponsible, misdirected, misleading, alarmist mess of a post. That's hardly surprising.
