Earlier quoted context omitted.
Twitter isn’t going to broadcast or link to tweets that were bad enough to merit a ban, for obvious reasons- they’re banning it precisely to avoid having that content be propagated any further.
This is circular reasoning, and it conveniently excuses any abuses or hypocrisy by the company by disappearing the evidence and not allowing anyone else to judge for themselves. From an outside observer, there is no way to distinguish between the claim that the ban is for "good reasons", or that the ban is a result of bias on the part of the company.
No it's not, because Twitter itself has presumably reviewed the messages itself. As a service owner, and therefore an arbiter, it doesn't need to allow anyone to judge themselves.
