Vod's opinion is that your opinion indicates a mental deficiency (something I disagree with - I think you're just a troll - but I appreciate Vod's warning nonetheless) and that you can't be trusted. That's really not a complicated concept. If you disregard all proof for Earth being round then (again - in Vod's opinion) you're likely to disregard e.g. proof of a Bitcoin payment.
This is such bullshit and a false analogy.
Just because he has a different line of reasoning on things we disagree with doesn't make him a scammer.
The trust system shouldn't be used this way, if you want to you could leave a neutral stating that the user believes the earth is flat.
Leaving a red tag on someone just because you disagree with him is very wrong.
@joerogers8 don't engage in a discussion whether or not the earth is flat, you will waste energy on tilting windmills
the discussion should be, whether or not it's right to leave negative feedback to someone for expressing a dissenting viewpoint
Although I respect Vod and everything he's doing on bitcointalk, I believe this act is very wrong.
