As for the data breach, the appropriate parties have been notified and also given instructions to avoid potential hazards from the breach.
I've owned an account with your website and even had a forum account too since essentially day 1 of the website. I had received no warnings nor mentions about this and as a long standing account owner of your website, I find it rather rude to not have been sent an email about this data breach and only to find that I had to re-validate my email address. If you want people to take you seriously then you should of sent a heads up email to every account on your website. Instead though I had to find out about this through this reddit post.
Next time something like this happens, sending a email to everyone would be much more appreciated.
