Did something like that ever happen to anyone ?My Tumblr blog disappeared (http://blog.gitwatcher.com).I've already emailed the support, but no response at all.(last) UPDATE ... in responce @Ciaran (see his answer)I read Tumblr's Content Policy twice and in my understanding, there wasn't any violation. Moreover I didn't received any email from Tumblr to the address I signed up with.(previous) UPDATE more infosFirst of all, the worst thing is that if I try to login, I get a suspended page: the server is redirecting the request for this address in a way that will never complete error page.That said, if you try to click http://blog.gitwatcher.com you get a Not found - We couldn't find the page you were looking for. ( 404 http error ). If you try to click http://gitwatcher.tumblr.com the same, you'll get a Not found - We couldn't find the page you were looking for. ( 404 http error ).If you run nslookup on both the domains youll get the following:Name:    blog.gitwatcher.comAddress:  72.32.231.8Name:    gitwatcher.tumblr.comAddress:  50.22.53.157where the last IP is:Name:    50.22.53.157-static.reverse.softlayer.comAddress:  50.22.53.157Moreover, I can reach the server responsable to redirect any second level Tumblr blog domain request to a custom domain name, so that server for some reason and without any warning doesn't do the job anymore:lsoave@ubuntu:~/rails/github/gitwatcher$ ping 72.32.231.8PING 72.32.231.8 (72.32.231.8) 56(84) bytes of data.64 bytes from 72.32.231.8: icmp_req=1 ttl=50 time=147 ms64 bytes from 72.32.231.8: icmp_req=2 ttl=50 time=149 ms64 bytes from 72.32.231.8: icmp_req=3 ttl=50 time=339 ms^C--- 72.32.231.8 ping statistics ---3 packets transmitted, 3 received, 0% packet loss, time 2003msrtt min/avg/max/mdev = 147.527/212.135/339.744/90.236 mslsoave@ubuntu:~/rails/github/gitwatcher$Why?
