First off, it's spelled "ridiculous".

Next, it's not for you to decide if someone wants to have multiple personas. It's also going to vary over time.

Here's an example taken to the extreme: because you have posted publicly (at least several times on HN), is it okay for me to decide that that fits my personal definition of a public figure because you have now a reputation of being kind of a tool and then proceed to investigate and post personal details about you?

I didn't think so.

It is harassment because it's not up to YOU to decide if a) he is a public figure and b) if he cares for such information to be shared.

You can couch it in different terms but I view this as much more self-serving than any else.
