I don't think so. By that logic downvoting someone to zero and making their rep negative would hide them even on hive.blog, is also censorship. Downvotes reduce visibility on Hive frontends. Normal users won't go to hiveblocks and see what's downvoted to dust.

Spam is also hidden for a reason. Good for UX but you can still see those comments on the blockchain level.

Why does peakd get to decide what speech is acceptable?

Because they own the frontend. Most DApps on Hive are centralized.
