I guess for LinkedIn it could matter most, because their only livelihood is CV and employer companies Data, if you steal a poor man's bread they are gonna be upset. It was dead as a social network long ago if it ever was, now their only asset is the data, so I guess their right to protect their only asset is legit.

I would suggest occasionally actually informing yourself of the wider world. Your very example of Google Maps in Germany - well, turns out Google had to give people the option to opt out: https://europe.googleblog.com/2010/10/how-many-german-househ... Same goes for web sites - robots.txt exists for a reason. If your crawler ignores that, well, I'd suggest talking to a lawyer.

I wasn’t aware that robots.txt had any legal meaning. Am I wrong?

I'd talk to a lawyer. There are presumably some legal arguments that might apply. There definitely have been cases revolving around it, but I have no idea what the outcomes were.

From a moral point of view: robots.txt states an intent, and intentionally ignoring that is not a nice thing.

And often, "not a nice thing" translates into legal action. So, if this matters to you, you should find an expert :)

LinkedIn takes plenty of technical precautions to block scraping. I’ve built bots that scrape them in the past, it’s surprisingly difficult as LinkedIn is very good at determining you’re a bot and blocking you. So it’s hard to argue that a service which is scraping LinkedIn is doing it without knowledge that they are going against LinkedIn’s wishes. Whether or not this is illegal is up to the courts to determine, and…

* That being said, I hate LinkedIn as a company and I fully support anyone trying to mess with them So it's fine to mess with them, even illegally, just because you don't like them? * convinces people to willingly provide personal information Convincing is not forcing, and in fact, you say "willingly" yourself. Any business convinces you to willingly give them money or other value. * sell at ridiculously high prices…

This might be one of the best replies on HN that I have seen. Spot on.

If it's not illegal, then scummy behaviour against a scummy company doesn't exactly set my moral compass off. You reap what you sow.

As far as I'm concerned, if the information is publicly visible on a site (not behind a login) and as long as the scraping doesn't cause performance issues or generate costs on the site, then it should be perfectly fine to do.

There, I fixed it.

Their desire to protect it is legit, but it doesn't necessarily give them a right to do so.

A long time ago, companies that were compiling phonebooks also thought that they could use e.g. copyright to prevent others from using that compiled data for commercial gain. They were wrong, because copyright doesn't protect "mere aggregation" of data, as courts have ruled.

In this case, LinkedIn is not arguing on the basis of copyright, so it's a different legal argument. But the essence of the case is they same - they want to have a business model around aggregating other people's data and then providing access to that data, while limiting what people who access it can do with it. They don't have a right to this business model. If technical means of restricting access don't work, or if adopting them means that they drive most of their customers away, tough luck.
