Are KBO balls juiced?

I admittedly haven't watched as much KBO baseball as I should be. In the absence of Major League Baseball, the KBO has filled a void for a lot of people. Discussions about the league make up probably half of my Twitter feed at the moment as more and more people tune in to foreign baseball to get their fix. 

But recently I've seen a few tweets regarding the possibility of juiced balls in the KBO.

#NCDinos starts off Week 2 with a walk-off W vs #KTWiz. There were plenty of offense thru out the league tonight. Are game balls juiced? Intersted to see what #KBO says tomorrow.

Ok, I’m now 100% convinced that old juiced balls are back. Oppo HRs at Jamshil stadium are rare. Already 2 in 6 games. Good hitting by Ramos, but this would have been an out last year. #KBO https://t.co/d9TKsKxNIE

We of course saw a similar controversy in MLB last year, with a new record for most total home runs in a season.

The possibility of juiced balls presents a couple of issues. It makes it harder to judge a player's success if there are variations in the ball from year to year. It also affects pitchers who wouldn't be giving up as many home runs as they are with the juiced baseballs. 

Of course, if the baseballs have changed league-wide, it's not as much of a problem as issues like steroids and PEDs. Everyone in the league is still on a level playing field, even if there is more offense than there would usually be. 

For now this is just speculation, and with such a small sample size of games played so far, it's hard to know for sure if anything has changed in the baseballs. We'll have to wait until more of the season has played out to see if there's really been a change.
