Well, I (& they) personally know people who are victims of Sven’s stalker like behaviour / issues / symptoms of a bigger problem

I see that a lot of the appreciation posts are also purely anecdotal. So are we contesting whose word has more value here or what anecdotal experience is valid/invalid or appropriate to share?

Someone very dear to me is a victim of Sven's stalkerish behavior.

What behavior? Repeatedly texting / touching girls decades younger than him even after being politely rejected on multiple occasions.

Very vague. Very, very vague.

When did all that happen to the person very dear to you? Here's me asking because I have a hard time imagining how a very frail person on crutches is gonna stalk someone.

You can pretty effectively cyber-stalk somebody even when frail, especially if you're an old time FOSS hacker who really knows how stuff works.
