UKCrypto has now proven himself to not be an alt. If Nubbins was wrong about him, is it not highly probable he is also wrong about the others?
He's likely wrong about UKcrytpo but probably not about the others. It's pretty obvious the other two are alts /shills just from their behaviour and BadBear will have some other evidence such as IPs tying them together.
BadBear has refused to offer any evidence, he just said "I don't care if you don't believe me." If Nubbins is willing to lie and abuse the trust system to try to intimidate myself and UKCrypto, why wouldn't he be willing to do so for the others? IMO BadBear left his rating based on Nubbins false accusations and just doesn't want to admit he may have been mistaken.
Considering that WC has said he uses a proxy service, an IP correlation alone doesn't prove they are alts of each other (as you well know, but don't let facts get in the way of your accusations). An IP correlation could EASILY happen simply because they use the SAME PROXY! This is not proof of anything.
I have seen zero evidence either of them are alts or shills. Just because some one stands up for another user does NOT make them an alt or a shill, and it is RETARDEDLY EASY to sling that accusation at people because it is basically unprovable either way, but the accusations are certainly useful for trying to intimidate and discredit people.
