well until the OP comes back which they probably wont, we will never knowthe only customer who "suffered an account suspension" here appears to be someone who actively gamed the system to extract fraudulent points. There have been numerous posts from other members who from time to time make returns, but none of them appear to have suffered an account suspension.........
for example 10 yrs ago I booked a flight for my GF at the time of 4 yrs a trip overseas using my points with her,
however after I checked the T&Cs I paniced because I technically wasnt family, as we werent married,
but according to other people ,apparently it was highly unlikely it was going to be a problem,
but yeah I was panicking for a while , because I did break the T&Cs
