Entirely irrelevant. YouFailAsAnAdmin is correct in what he says. Yeh, it might hurt a little, but he is correct.
Not impressed at all with the postings from this site's Admins in this thread.
The minute you start putting banners on the forum, the "we are not commercial" argument fails. You are earning adsense commision off your members, so please don't plead poverty.
You contradict yourself when you correctly point out that even with massive resources, a dedicated hacker will still get in.
So, that would be an Admin password then, and your IPB admin logs will reveal exactly which admin did this?
It's looking awfully like your own Admins didn't take your own advice.
I run a busy forum and have had my share of headaches so you have my sympathy, for what it's worth - but I really hope this is not an #Admin password being so weak it was brute forced, because that is what you have described,
