Steam account suspension?

Hi. I have bought an old steam account from sythe (5 Digits) at 2014 i think.. everything was fine until i started playing cs 1.6 again. When i join a spesific server with other players it displays my steam name and steamId in the chat. And 2-3 people started asking me where did i get the account from, its a cracked account etc, i dont know why but they are autistic and told me that they gonna report me in steam. Like wtf? Can my steam account get suspended for something? I havent done anything and they just reported me for no reason... Some help would be great pls
