If this isn't the right board, please let me know so I can move it.

I have a simple question, if I mistakenly post data such as my personal address, private key or any data that I later want to hide, and I contact @ and he delete it, will both sites comply with this deletion?

What can I do if both sites do not comply with this, and what is the role of the forum in this case.

We can ask more questions, but they will revolve around the sites that collect, analyze or keep forum data.

Add to that, do they keep my IP address? It's easy to get to because I'll look up my posts.
