I do worry, because the more places, your data exists, the risk of your data get stolen increases. If someone does not care, he will face the consequences, of an identity theft. Before many years, there were no identity theft issues, because there were minor places, you should give your data. Nowadays, many say scam avoidance, but for me, the gain is less than the pain, so I see no reason to give my personal data. If you ask KYC for a bounty, I won't participate. If you ask KYC to offer a service, excuse me, I can live without it.
