The problem is that we are using bitly branded short domains as a url shortener. Our branded short domain is d.so.city
Now whenever I search site:so.city on google, all the d.so.city links appear even before the genuine site urls. I don't want the bitly url's to be crawled. I know this can be easily done through robots.txt for the subdomain but we dont have access to subdomain's robots.txt file as it is fully linked with bitly.
I have also tried parameter blocking from google webmaster but no luck there also. I have also gone through Bitly documentation but couldn't find anything relevant there as well.
Below is the snapshot of how my site search looks right now:
