Can you stop someone shrinking my URL?

Yes, we can if you submit a full DMCA notice here:

https://dmca.adf.ly/

This needs to include your name / company and a legal declaration. We will then block it. DMCA notices that don't contain all the information required will not be processed. For more information please see:

If we block a URL on AdFly it means no one can shrink it though - including your own account.
