It doesn't matter whether he did or not.

All that matters is that it was possible to do so.
Any coin that allows for insta-mining should be strongly frowned upon.

There is little excuse, in particular for a new PoW,
for not having an insta-mining-proof distribution schedule,
where it takes at least a week for rewards to climb to non-negligible levels.
Preferably, rewards should not peak until a month from launch.

I realize that very few coins do things this way, but I think that just goes to show
how few coin developers truly care about fair distribution.

And if you think a developer is fairly entitled to a share of coins, then there are
simple ways to limit it to a reasonable 1% or less.
