This is not a bug. This is how it works.
For example: You can switch between any Steem Blockchain posts with the name like below.
https://utopian.io/rmb/@rmb/links-in-busy-org-activity-view-are-not-correct
Look here, I have added iloveutopian: -
https://steemit.com/iloveutopian/@rmb/links-in-busy-org-activity-view-are-not-correct
That is only the category which can be changed freely by the users, so it can be manipulated to use in different steem platforms.
Most important part is :
@rmb/links-in-busy-org-activity-view-are-not-correct
Which should not be changed.
For the reasons above, I won’t be able to accept your contribution now. Thank you very much for using Utopian platform to make this contribution. Will be waiting for your next contribution.
Thanks for the review and the information
