I said email change raises red flags, it doesn't get you banned until you change email+pass at the same time, yes you can change ip but if its to a different country without notifying them first then you will be banned.
Your trying to be kind giving this what.cd account away but this could hurt the person you give it too, they ban 98% of all accounts that trade hands.
This could be very bad for whoever you give it to, maybe even get them a global ban
