I see a different Bitcoin address. I recommend people visit the site and not use the address random commenters on the internet post. Not saying the parent comment is up to something, sci-hub may have rotated the address for whatever reason. The one I see starts with 14ghuGKD
EDIT: Ah, interestingly, the 1K4t2v address appears on the scihub.cc homepage, but not the donate page that was linked
They don't even have a valid certificate for that domain.
BUT interestingly, on a US (DO NYC) server or my house (US/Comcast):
$ curl http://sci-hub.cc/donate
<p>Please donate to Bitcoin: 14ghuGKDAPdEcUQN4zuzGwBUrhQgACwAyA</p>%
however, on a French (OVH) server:
$ curl http://sci-hub.cc/donate
<!DOCTYPE html>
<html>
<head>
{cut for brevity, a fair amount of HTML here}
<p>Please send donations to bitcoin wallet: 1K4t2vSBSS2xFjZ6PofYnbgZewjeqbG1TM</p>
{more HTML}
DNS reports that the domain's IP is 31.184.194.81 from all tested locations. I get the HTML page with the 1K4t address over tor as well
This is a another good cause that I would find worthy to donate to.
Edit. Ok, found it:
http://www.sci-hub.cc/donate
Apparently, only bitcoin donations are possible at the moment. BitCoint Wallet for donations: 1K4t2vSBSS2xFjZ6PofYnbgZewjeqbG1TM
