But the people whom you're talking to you just don't know how many scams they've promoted or how many people they've scammed themselves. So there's no case of defending yourself here.
I, personally, know how many scams I promoted and also how many people I scammed myself: 0 (
zero).
Of course, what I am saying, you are not to be trusted no matter what. The idea that those old scams were gone does not mean that the scammers did, and they could have very well created new accounts such as yours (who knows) and now they say oh look at those old scams they should be all gone. And the proof is all of the scams we see with the "trusted" members.
Now definitely like everywhere else there is still some people who never scammed but most of the time it's a matter of chance to fall on someone who does/does not scam.
