My Domain Redirecting Someone Elses Web Page

I’ve tried to open my blank web page (divxhell . com) but it’s redirecting another web page (NSFW !! your - sweet - girls1 . com) and domain not changing. I got this address from page source. I don’t know whos page is this! There is no file on my FTP, I’ve deleted all files but still redirecting. What should I do?
