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.
