Any method to check if my website has been penalized?

Greetings community, I hope you're doing great. My adult website was getting around 4.2k visits everyday with a constant grow but by Sept 15th traffic started to go down in a very progressive fashion. I'm getting around 1.6k daily by now, and Im not very sure if this could be the effect of a penalty. I checked with the site: footprint and most of my pages are still indexed however I noticed that one of my top posts (which ranked 1st for certain keywords) was vanished from SERPs.

Is there a way I can check if I'm at the receiving end of a Google penalty?

You're not penalized. Google have some problems lately, I guess it's because of that.

Yes maybe you're right. BUT if I don't pay for ads (and I wont), you will not pay.. Nobody will pay, and there is everything like before right?

Google has no interest to show bad results like he shows at the moment.

Because of that I think it is some bug or something.

And if you're right than big G is in a problems... If continue with showing bad results will lost a lot of visitors.
