For those being banned without explanation, can there not be any sort of legal action taken? IANAL, and I've not gone over their ToS with a fine toothed comb, but I can't believe they can essentially eliminate a primary source of income (for some people/businesses) without an explanation, especially when no ToS violation is known.
Wouldn't this almost be equivalent to being terminated from a job without reason (and isn't that also subject to legal action)?
