There was a vote on this issue up in the RS slot holder boards, so many of us already know about this. Primarily the reason was to help clear up the banlist which was becoming too overwhelmingly large to manage, since tonnes of the bans were for stupid newbie rule violations and advertizing and whatnot, most of which the players who were banned probably don't even play NS any more.
The resers also thought that many of the banned players possibly deserved another chance, just that they quite possibly just never bothered to make a PR thread or what not. Hopefully the banned players who would come back and grief given the chance have moved on and have better things to do these days.
The news posts that have been posted are as far as any of the offical representivives of the comunity are going to go in terms of announcing the clearing of the banlist as far as I understand it, we discussed making a large offical announcement, but most of the members of the comunity thought that trying to make a public relations grab out of something that was mostly being done for convinience anyways was probably a bad idea.
Anyways, if you were banned in the past and you are back around and reading this, welcome back to the comunity, I hope this time you can show that you have what it takes to stick around. We are still watching, remember that.
[edit] LB, I remember there was some discussion about weather confirmed hacking bans would be be lifted or not. I know many of the banned players I can probably name, but did we end up lifting hacking bans in the end or not?
