i ordered a fiverr gig which claims to do .edu blogs. the results i get: xxx.edu.tr.vu what is that? i looked it up, .tr is turkish, .vu is another country. what in the world is going on? how do you add .tr.vu at the end of a famous .edu university domain? this has nothing to do with that university, does it? it seems to me, he bought a domain tr.vu, and add a subdomain 'xxx.edu'? will this kind of backlinks still be useful?
