Address redacted on warranty card - impact?

[agentq]

Hi all, I've bought/sold both grey market and from ADs, but I'm considering a purchase and noticed that the seller (or someone earlier) has crossed out the name/address on the warranty card.

Is there any meaningful impact from doing this? I see how one would want to do this for privacy reasons... maybe this is something I should consider if I'm selling a watch with my name on it?

Any insight would be appreciated. Thanks!
