The evidence that there is compromised data comes from screenshots on Reddit that are claimed to be of a chatroom where someone is posting something that looks like personal data which contains information that the site says they do not collect. This isn't exactly a smoking gun.

Given that they are the target of a cyber attack, likely one that is politically motivated, I would assume that the attackers are not above spreading disinformation on social media.
