Yeah, yeah, this IP is already silently blocked for 1 week, just because ONE EDIT after previous (24h) block expired.
And this is not a spam. Site in question is relevant and can be added under WP:EL rules, and this is not only my opinion. But I see you are trying to game the system now to remove it for good. That's good, actually! Please, add this link to blacklist, please, please! You will effectively censor it on all wikimedia projects AFAIK, so it will be quite funny to watch the ensuing drama. ;-)
