Off the top of my head, here are a few: 
Businesses: Transwiser has not been a scam. Blocktrades has not been a scam. MetaExchange has not been a scam.  OpenLedger has not been a scam (although some of its ICOs could be).
Workers: Svk, myself, Xeroc, cass, and others have run worker proposals that have not been scams.
At least we will never reach 100% rate of scams.  

 Good to see you posting, Ander!
