I haven't seen this mentioned on the board, nor do I appear to have received an email from QuinStreet (owners of AntiOnline). However, I can confirm that there has been a data breach on QuinStreet properties which includes this board.

QuinStreet

In approximately late 2015, the maker of "performance marketing products" QuinStreet had a number of their online assets compromised. The attack impacted 28 separate sites, predominantly technology forums such as flashkit.com, codeguru.com and webdeveloper.com (view a full list of sites). QuinStreet advised that impacted users have been notified and passwords reset. The data contained details on over 4.9 million people and included email addresses, dates of birth and salted MD5 hashes.

I can confirm personally that an email address used for AntiOnline has been found in the breach data, however I do not appear to have received any email advising of this. My password did require a reset to login however.
