i suppose it is not a tracker nor it looks like , i think gamers got to see it m not ..
steam accounts can be recovered don't do this trade guys.. unless he's offering to gift you games it's a risk. doesnt matter if you change the email address or anything, there are ways to recover an account you create on steam, altho i forget the details because ive never done it. happened to me before tho
you contact steam with the credit card you paid with or some other identification and they reset the pass and email
you can always give the games as a gift
