Vac ban rust steam

I decided to use the site Playkey.net service-play in Rust (On Steam, I have it). I bought myself an hour subscription. Played, all is well. I go yesterday on Steam, I see I was given a VAC BAN in the game Rust. I could not use Chita, of course, because I played from the Playkey server. Please sort it out.Thank you in advance!
