"Asking for the price of a gun doesn't mean that I am buying the guy and putting a bullet in a random guy"
Asking the price of the gun shows that you have the hidden thought in mind about buying it later on and possibly commit some crime.
I know it feels kind of scam but I was not into it.
Let me make this clear to you. Buying accounts on bitcointalk is not illegal and it goes around nicely. Sometimes they are legit accounts and sometimes its scammer tactics to scam newbies (at least I dont expect older members of the forum to fall for them but they also get fooled)
However this practice is looked down upon since buying an account only leads to people scamming others taking advantage of the trade history and the shitposting which plagues the forum. Even if you did not buy its important to mark the "potential account buyers". That is why you deserve a red mark now.
I will also be leaving a negative trust on your account.
