Well I'm up for trying it but to be honest I think that board would be pretty dead without all the blogspam so it might as well be locked/archived. How many threads are on the first page or two that are from notable sources? I just checked the first ten threads on there and all but two were from crypto-based sites and the other ones were not from sites I'd call notable sources.
Isn't that the point... if you remove the spam then more threads on the front page will be from notable sources.
Locking the board would be giving in to spammers.
Not really. The board has served its purpose long ago. It was created when any press article was exciting or indeed notable. Now nobody gives a shit what the mainstream media has to say. Any decent article can be posted in the main board if its worthy of discussion. Besides, there are plenty of measures that have been implemented because of spammers: Activity, merit, signature restrictions, PM restrictions, certain boards not counting towards activity/post count, newbies can't post images etc so if this is 'caving in' then so are all those.
