Worst ELO ever in history I have a lot of questions about ratings, which are sort of connected, but I think I better split them. This is pair 1.

I googled a bit: By definition, ELO&gt;100, and someone said (chess.com) he knows a dude with 200. I'd prefer &quot;official&quot; FIDE data to hearsay, though - does anyone have it? (Remember ELO began only at 2000 when it was introduced!)
Note that I can easily search DWZ (German ELO equivalent), but only for a current year.
Assume a chess program that knows the rules perfectly, but makes strictly random moves. I'm sure that experiment is so simple that it has been done yet in the computer chess league - so what was the ELO result? (Note that you can't compare this with a human who just learnt the rules. That moves will be very nonrandom, I'd bet on pawn moves...)
When I played magic the gathering, at a time when they used ELO-style ratings, I did play from time to time against the lowest rated player in the country. He was a nice chap, and very enthusiastic but I suspect he was on the “spectrum” as they say, and this makes me less eager to identify very low-ranking chess players - it doesn’t seem kind
