BitTorrent allows untrusted users (read: industry plants) to connect and slurp down direct IP addresses to swarm participants. It's an unanswered legal question whether low-level uploading (such as the percentages one would get as a "leech", connecting to the torrent and then disconnecting immediately after completion) might fall under "fair use" or "fair dealing" statutes in various jurisdictions.
US-centric here: I feel that uploading a small percentage of a file as a condition of downloading the whole thing may very well fall under fair use - most BT traffic is noncommercial, the portion of the covered work uploaded by "leeches" is very small and probably would be covered by the "30-second" rule often quoted in fair use discussions. The only really arguable point is the "effect on the work's value", but then again an average leech is not uploading enough of the work to have that much of a material effect on the work's value.
In Germany at least, uploading even a single byte of content is illegal. We don't really have Fair Use here; there are only few, very narrow exceptions.
It is also not even required to show that that single byte was uploaded, your IP getting logged as part of the swarm suffices. The burden of proof is on you now. It was much, much worse than in the US.
While all this is technically still true today, a new law a few years ago luckily mostly blocked the path. It was badly needed, because the situation was horribly abused by law firms.
Of course Telco's can choose to be involved, perhaps accept payment to lookup and snitch, etc. but for the most part a number of ISPs in Au just wash their hands of devoting resources to play connect the dots for others.
In Germany, this was the case, too. So this happened:
1. Copyright holder files bullshit charges against the IP holder.
2. Police investigates and for this purpose gets the personal data for the given IP address.
3. Copyright holder gets personal data of the subscriber from the police.
4. Copyright holder aborts charges so police stops investigation and is no longer involved.
5. Copyright holder contacts the subscriber to extort money.
Police complained about the many bullshit charges, so of course a law was made so ISPs had to give out personal data directly to the copyright holders.
Same in Japan. There's allegedly someone making big bucks going after bittorrent users, straining ISP abuse teams and judicial systems. Interesting that Germany has laws against that.

What if someone would release software that would connect to random swarms and not upload or download anything? Would they still be criminally liable? You could disguise the purpose by saying it's measuring swarm diversity.
It's a mistake to assume courts need "proof" for a ruling. It's totally sufficient if courts find that it's just the most likely. "Not guilty until proven innocent".
If you receive child porn in your mailbox and the package is caught, you better have a really good story. Like, prior documented proof of harassment.
In regards to your question, and Germany specifically: Media companies hire specialist lawyers. These lawyers prefer to sue in Hamburg, where the courts are known to be very media company friendly. It's just not likely that you ran some experiment and didn't upload anything, so you better have it documented well enough to convince the court.
I would think that at least a couple dozen of those 100 random people will report to the police. These reports can be used in court, and may or may not convince the judge that you're also one of the victims. You'd also think there was other circumstantial material to be used either arguing for or against.
Compare to torrenting: Not a dozen of 100 people will independently and proactively report that they ran some "experiments". You're on your own with that story, and it sure sounds like an excuse (to me) even if it were true. Plenty of people end up in jail (or with fines) being innocent. Real world is not the movies. Real courts do not need 100% certainty to "prove guilty according to law".
Back in the day, this would 100% get you letters from law firms that extort money from you (usually around €400 to €2000). Failure to pay had a fair chance to get the case in front of a judge. You will have argue with him that you did it for fun and did not actually up/download anything.
If the judge does not believe you, expect to pay something like 3-6 months of income. If he does, you only have to pay your lawyer (the opponent will not). Back then, I'd say it was a 50:50 chance, provided you have excellent documentation and a good lawyer.
That's awesome! So a media company technician can plant IPs and ruin their competitors lives. No wonder this country keeps failing to get a tech industry.
Yeah, there is no threshold to how much copyrighted material has to be uploaded. Any upload suffices to make it illegal. If I recall correctly, the intent/justification was to ensure that uploading a single song, or half a single song, is captured by the law, but of course it was written in a stupid way.
“Here’s byte 0x67, which is at offset 0x729B1A38 of Copyrighted_Blockbuster.4k.mkv, as requested” is different from “here’s byte 0x67, and it’s the first byte of my text response to your comment”.
IP Firms have automated bots to send mails to abuse@provider the moment they see you even getting a file list. My Hetzner server got taken down after an abuse complaint from McGraw Hill saying that I downloaded some dogshit management book by merely connecting to DHT.
Hetzner is in Germany, the server is in Finland, the accuser is in the US. The only way to win is to either move away, or lobby for your countries to stop respecting US copyright laws.

This is not consistent with current Fair Use application. The TL;DR is that the use must be for a new expression that is protected by either the 1st amendment or copyright itself. I don't know of a single case where it has applied to mere distribution. I would be astounded if there is such a case because that isn't within the expressed purpose of the doctrine.
