User Impact
Email address is in plain text, so affected users may receive Spam emails. They believe the data was not widely exposed and they also confirmed the exposed data is from July 2012.
Right now there isn’t any evidence of unauthorized logins occurring in relation to this. No plain text passwords were exposed, but it is possible for this data to be decrypted (even if unlikely). As a security precaution, we have reset the passwords for all affected users. We recommend that all users change passwords on other services if they are shared.Disqus says.
So if you started using Disqus after July 2012, then your account is not impacted by the breach.
