That link has your si in it. Your si is a tracking code Google uses to determine who clicked on links you shared. They want to know who your friends are for their social data models.
I had to explain this similar concept to a co-worker who always puts his tracking info in his parts orders. He didn’t understand until I started asking him about firearms parts he had been browsing on his own Amazon account.
His links are now sufficiently sanitized.
Hold on… how were you able to find out about his amazon browsing habits from a tracking code? I thought end-users wouldn’t have that information but only amazon themselves (+ their 391712 friends).
Additional recommendation: use https://linkcleaner.app or Léon URL Cleaner (Android) to automatically remove those pesky tracking parameters.
