Legally? No idea. What might be adequate protection in the country your instance is hosted, is probably unenforceable in another country where a federated instance might be.
Technically, you could try by using your own, self hosted instance, and not federating with others, so they won't be able to scrape your content as easily.
But realistically speaking, your comments are possibly more likely to be scraped on Lemmy, since it's so much more open for bots, and your content is replicated to much more servers, not all of which may have noble intents.
My brother worked for such a Dutch company (ASM) and often got sent overseas to supervise the setting up of the production lines with these machines.
He mentioned when he'd get sent to Asia, the workers would make sure to get it done over a weekend, while implementing the same setup would take 2 to 3 weeks in the US. In part that was due to the working conditions mentioned, but also simple lack of planning in case of the latter (things would grind down to a haalt because certain changes would need to be made, and the person responsible for the decision wouldn't respond for hours or days, etc).
Side note: while 36 hour work weeks are common in the Netherlands, 40 hours is still the norm in my experience.
