Bro... you know how hacking works right? You making me question that-
Well, assuming you got no idea about what hacking means due to your old messages, here is the definition with bold letter for importance-
A security hacker is someone who explores methods for breaching defenses and exploiting weaknesses in a computer system or network.
Now why did I bold this phrase? Cuz that means a hacker is a person who tries finding fault in strings of code and security and manipulates it in such a way that they can breach into other people's information and privacy, this means that they won't come and annoy you with "PlS tRaDe AcCoUnTs :(" but instead they will gain access to your account without your knowledge so don't be so paranoid unless and until you don't blindly trust anyone online, you are fine because hacking isn't easy or simple at all and only a very advanced and dedicated programmer can pull it off so don't worry just don't trust anyone and don't think somebody will magically hack your account or your info it ain't that easy.
Not to mention the fact that hacking is illegal in most countries irrespective of the fact that you hacked a game or hacked somebody's bank account, both are punishable offenses so not many people dare to hack due to that as well. (Unless you play games with .io in the end those games are easily hacked because -
1- they are just easily made in comparison to other types of games like mobile game or downloadable games.
2- they are easy to manipulate due to reason 1.
3- the devs are more casual of .io games and most of them don't take hackers seriously but the ones who do, make sure the hacker will get punished.)
