This kind of thing is why I wouldn't touch a site like that. Websites, service providers, and internet-connected software that collects data from you can't be trusted even a little, so I avoid them to the greatest degree I can. The rule of thumb is that anything you tell to them, or any data you have put in their custody, is at risk.
unsure why you are being downvoted. this is universally true. your data is either being actively shared with partners, or inadvertently shared in the form of weak security, exploits, wide-open buckets, etc.
Europe has laws against misuse of data from visitors, so it’s generally safe to visit such websites.
The fact that this is on hackernews means this case is the exception, not the rule.
