It might be that some of them are just wright shills/socks. But they're there, I down rate them when they're obnoxious about it.
Here are some examples:

There are some more in my ratings history... and many more if you go look under some rocks around here.
yeah, i have seen these users but to be honest i always had a hard time believing they truly believe in BSV nonsense. even the BCH camp don't believe in BSV and Craig's scam.
the only possible reason i can think of is either being a shill or having some sort of personal benefit in it.
