Agreed. However, why did exchanges list this BSV? It is head shaking because everyone knew already that it is a scam. The listing might have given it an appearance that it was being supported in the community. This is how scams trick people. If it is listed in reputable exchanges then it might not be a scam type of attitude.
Do you think that the people behind all those CEXs have a moral compass at all? Their only mission is to make as much profit as possible and they don't choose the way to achieve it, even if it means that at some point they will support any BTC fork, be it BCH or BSV, or one that may appear in future (say BRB - BlackRock Bitcoin).
We have to accept once and for all that CEXs do not exist to help Bitcoin (although they have an influence), but they are companies that only provide cryptocurrency trading services regardless of what the coins/tokens are called or their purpose of existence. What I want to say is that regardless of whether they know (or assume) that some token/coin is a scam, they still agree to list it because they are probably paid very well for it, and in addition they will make a profit as long as clients trade with it.
