Just so folk know the whole story, someone on the site claimed that they'd breached ResetEra's data and had emails/passwords, etc. They claimed to have messaged the admins from multiple accounts as "proof." ResetEra responded, saying that they looked into it and found no evidence of a breach, but did find evidence that the user in question is a known alt-right member with a history of harassing ResetEra members. They attributed the multiple accounts to the user having access to public information stolen from breaches on other websites.
The same user has now posted from several other accounts, posting dox'd (and potentially false) information context-free collected by places like Kiwifarms to try and harass B-Dubs, the site General Manager.
If folk don't have 2-factor security set up, it might be a good time to do so. If you're using an old password that may have been scraped by hackers from a different website (maybe even NeoGaf) then it'd be worth changing.
