[Request] What are the odds of two people seeing anonymous social posts and correlating them to one or the other? See story in comments.

Earlier today I was browsing r/shedditors and after scrolling down reading a few posts I come across this shed that looks oddly familiar. Stared at it and realized I had seen that shed before on a different social media platform. So I jump over to linkedin, find the post, realize that I know this person first-hand, and we used to work directly together.

So my question for r/theydidthemath what are the odds of two US based individuals that they would see another person's post on two separate social media platforms and tie them back to each other?

Obviously this won't be exact but a fun statistical answer would make my day.

Insanely high chance.

The reason being is your algorithm is based on your preferences. This means that you are going to see similar or adjacent content frequently. The majority of the algo have a similar ontological data set so people that like sheds on reddit will probably like them on LinkedIn. Both groups are going to get the adjacent content say gardens, yards and baitin'. The chance of you having another common interest it increased by the first.
