ETCV on the other hand was not quickly detected, but its team was anonymous, which i feel is enough to suspect them of scam.
being anonymous is not a reason to suspect someone. suffice it to mention that Satoshi Nakamoto (the one who created bitcoin which is the start of all this) is still anonymous to this day.
as for all these forks, it seems to me that certain people are trying so hard to both make money by doubling their coins and also at the same time try pumping ETH price. they didn't succeed at either so far which is one of the reasons why they are failing.
