I assume this is due to the recent attack?
If I remember correctly, they've done this multiple times before. It's why the members list doesn't reflect the amount of people who have actually joined this forum over the years. I'm guessing that what makes this different is that the last purges were probably just really, really inactive accounts, while this purge is getting rid of accounts that have just been inactive for 2 years. Or not, I'm just filling in the blanks, maybe a mod could fill us in.
And I too support the "Fonger Conservation" effort.
