Re: Potato, potatoe
"Reading anything they post", assuming that's authorized access, shouldn't be included in the definition. I wonder whether the report authors did so, though I'm not curious enough to bother reading the report itself.
I occasionally see messages posted by a former partner, because she sent me a "friend request" years ago, and I accepted it since I had no reason not to. (I never post on social media myself, but I do occasionally check one or two accounts to see what might be happening with family members and the handful of others I've added.) I'm certainly not "stalking" her in any useful sense of the word.
Similarly, I can't muster much concern about people doing online searches for those they are, or were, in relationships with. If the material is public, then it's public. There's a vast gulf between that and either invasive use of IT (like stalkerware) or physical surveillance (even in public spaces).
