I think it was something to do with changing their views on adult content, or something like that - to be honest, I didn't pay much attention so all I have is a vague memory of them saying "sorry, we'll try not to be such dicks." Or words to that effect. And then they sell the site to the Russians (thereby ensuring that all of the spam to my old email address was in Russian - seriously, I miss spam about enlarging my non-existent penis) and cover the whole site with ads.
I've made an account on DW - still almighty_frog, because I'm just that imaginative - and I love how my interests list shows that nobody else listed d.grayman, a fairly popular manga licensed by Tokyopop, but a decent number of people are interested in some particularly obscure j-rpg games. XD
