While this website is really blatant at violating copyright, let me warn you that linking to their site on a big site like islcollective.com, ironically, just makes them stronger and appear higher in Google search results, since Google takes linking as a sign of prominence and popularity. The more prestige a site has where the link is placed, the more useful it is to the site being linked to. So as long as you don't want to help a rogue website, please refrain from linking to it here.
I think what should be done is authors (and other users who care) should send a message through the site's contact form to remove infringing works (but I guess there are thousands of such uploads, so this may be in vain). Also, authors may try contacting the Internet Service Provider (ISP) or domain provider of the website and request blocking. The ISP or domain provider can be found simply online. I looked it up and the ISP is based in Turkey and called "Ihlas Net".
It seems the whole site is based on its creator's anonymity, so I think the only real chance of stopping them is to file for blocking of access with their ISP. While I am not familiar with laws in internet laws in Turkey but I think the more people request blocking, the better the chance that the ISP will take action.
