Comment:
Cex.io and Ghash.io are services you can use with one account, but are managed and shown as two seperate services. That's why the deletion-method and the support is exactly the same. Splitted it up into 2 entries to let users search either for ghash.io or for cex.io to find the method to delete without being redirected to another entry on justdelete.me.
