PSA: They held the tips for a while to see if the creator signed up, and if not sent the crypto back to the user. If it even was the user's, they put up a pool of the stuff out of their own pocket to jumpstart the tipping service and the whole thing might just be over the allocation of that pool, I don't remember the specifics.

In any case no one lost their stuff, bad UX was critiqued and bad UX was fixed.
