I get what you’re saying. Fair enough for the posts and likes received. A little harder for the likes given, but still doable. “Topics viewed”, “Posts read” and “Days visited”: That can’t be known by anybody exterior to the site, and probably the privacy concern of the OP you’re searching for.
On the contrary, I find this unfortunate (having a private profile myself). I would be OK, and would love this to still work (we’re talking of “xxx is typing” you see when someone is writing a reply, correct ?)
