If this is an STO i doubt that this is a scam. Because before having or to be called an STO they need to have tangible assets and theses allegations if clearly a form of STO boycoting since it is going to replace the ICO stage. They might be scammers that does not want an STO before offering the coin to the industry and will eventually run.
Good point, STOs cannot simply take funds and run. There is a heavy process involved with authorities and excecutives become very accountable unlike in the case of ICOs where most can run and few ever pay the price. So if they really have sinister things in mind, why would they be so retarded to do an STO in the first place?
