Indeed, when you think about it, everything you post or do here can't be deleted, so scamming or doing something bad is not a good idea for your future reputation, especially if you reveal your real identity.
I see a lot of people who chose to do better with their postings and actions when they got exposed of scammy activities, but I tend to remember their past and I never truly trust them in the future, because who knows what they are actually up to in the end...
