The two projects you are referring to, are there still on exchanges, are there still trading? Is the discord community for those projects still functional? If yes, if people are still selling their mn rewards, if the exchanges and mn services has not delisted those projects then absolutely you know nothing about what is called scam and what could be termed failed project.
Why would those exchanges delist their main source of income? These three projects LPC LGS and now this one washtrade 100 BTC daily while 4 BTC would buy up the entire sell side on any of the exchanges it is listed on. Take the trading fee of 100 BTC a day and multiply that by the time these projects exist to give u a rough idea of how much this benefits the exchanges it's on, not to mention it brings those exchanges to a higher place in the ranking of exchanges ranked on volume. Stop trying to debunk this as being no proof or fud, bitcointalk should alter it's rules so these obvious things are being shut down.
