Ah yeah, you're correct, sorry. I had only checked transactions and blocks at Blockchair, never addresses

Now okay, one could argue that if they respect their own Privacy Policy, they display third-party "risk scores" as a service to the user, without transmitting visitor information (IP adress, browser fingerprint etc.) to these third parties. But that's where the "vague points" in the Privacy notice I mentioned here -- that they only use personal data to improve their services -- could be a loophole to indeed transmit this information in real-time to the risk score analyzing companies, because their risk scores "improve" the service of Blockchair.

Even if they don't do that, at least it is a big temptation for the users to click on these risk score ads, which open the chain analysis companies' websites -- and I think if you do that with your own addresses, then that's the moment they'll have the visitor information they wanted.

I can totally understand your discomfort and that would be also a reason to not recommend Blockchair.

BTW, I'll add recommended block explorers to the OP from now on (only really convincing one until now is Mempool, Blockchair may be better than average but needs a warning).

And @all: I know of course that the best way is to host a full node and run a self-hosted block explorer. But that's not the topic of this thread, I'm searching for services with a "better than average" privacy.
