6. Hi, sop. I try to repeat this warning when necessary. Remove the tracking info in the URL.

Substack will take the information after the first "?" in any link and use it to personally identify you.

In this case the attribute is the "r=xxxxx". When substack pulls up the link it will show your name. In your case it is just a first name (I guess) but sometimes it may be more than people want to share.

Edited to say: Usually links will work fine with all information after the "?" removed. Some sites (major news, financial, etc.) may not. It doesn't hurt to test the truncated link in your browser before.
