?leadSource=reddit_wall# is one example on Bloomberg articles when they are opened from a Reddit post.

Can you share a specific place to find this?

https://www.reddit.com/r/europe/comments/14xjdtu/erdogan_just_doomed_turkeys_eu_membership/

When you open this Reddit link and then click on the shared article URL, which in this case is https://www.bloomberg.com/opinion/articles/2023-07-10/erdogan-s-nato-sweden-blackmail-dooms-turkey-s-eu-membership, you will get a ?leadSource=reddit_wall at the end of the link. So the full link becomes like this:

https://www.bloomberg.com/opinion/articles/2023-07-10/erdogan-s-nato-sweden-blackmail-dooms-turkey-s-eu-membership?leadSource=reddit_wall

Sometimes you may get a #(code) instead, like in my case, #xj4y7vzkg. So the full link becomes like this:
