Not everyone has the technical ability or resources to determine if their data is present in the leak, and I suspect many people who were exposed in this hack appreciate the work being done by those like whoever made that spreadsheet, and Troy Hunt and the other folks we can thank for Have I Been Pwned.
If you want to assign blame, it is reasonable to blame the incredible irresponsibility and/or ineptitude at Epik that resulted in such an enormous amount of data being stored in such a poor way. It might also be reasonable to blame those responsible for exfiltrating the data, though with security and data retention practices like Epik's my only surprise is that it didn't happen sooner. But blaming researchers for reformatting or sharing their findings from widely-available data is frankly ridiculous.
As another poster aptly put it more than a few pages back:
There is certainly reasonable criticism of reporting on this particular episode, and of reporting on Epik in generalโfor example, I've seen frequent errors (usually in breaking news) in whether Epik is the registrar for a website or a webhost over the years. And if there are journalists who have written that, numerically, most Epik customers are far-right, then that should be criticized (and corrections submitted). But it seems bizarre to me to fault journalists who have described Epik as a popular choice among far-right groups and individuals, or as a company known to service the same when they have been deplatformed by others. It seems to me that Epik has chosen to make a name for itself and increase its profile through vociferous support of projects like Gab, and Monster's (and other Epik employees') various statements and appearances supporting right-wing individuals. As recently as two months ago they were
rubbing elbows with James O'Keefe, it seems. You're quite right that there are probably customers whose information is in the leak due to domains bought before 2018, and who may not have realized their previously fairly low-profile registrar might suddenly take a public turn to the right, but it seems to me that it is
Epik who is responsible for earning this reputation.
Anyway, now that I've responded to the ping and said my piece to the reply I will leave you beโI am cautious of appearing to intrude on your forum uninvited, as I am not a domainer myself. You know where to find me on Twitter if there's anything I can help with, or I will respond to pings here (albeit slowly and often only several pages later, apologies). Best of luck and best wishes to all.
