Is the Chicago reddit getting astroturfed by NASCAR?

Currently there are five PRO nascar posts:

• I invite everyone to turn on the NASCAR TV broadcast
• NASCAR crew members help fix a car's bumper after it was involved in a fender bender across from the garage area on Lake Shore Drive
• Unpopular Opinion, but i think the NASCAR races will be awesome
• OK Chicago,this Nascar thing is fun, Now do Formula 1
• This checks out…(Randy Sax guerilla marketing link)

and three ANTI nascar:

• Meanwhile, we’re doing 15mph on 90/94
• Worker dies while setting up Chicago NASCAR race
• Chicago’s Nascar Weekend Offers Headaches, Little Economic Gain

Two of the pro-nascar posts are obvious guerilla marketing (the "LSD pit crew repair" post and whatever that Randy Sax thing is). One of the Anti-articles is just news about an unfortunate event.

I think Nascar has hired social media PR/sock puppet groups to astroturf Chicago reddit. I wonder if it's the same people Paul Vallas hired...
