So, do people think Trump is going to be a one-off, or is it going to become a regular occurrence that politicians that are deemed to be beyond the pale get digitally annihilated?

And if the latter, only losing politicians, or politicians still actively running for office?

Not having access to social networks would obviously be a huge disadvantage for a candidate. Arguably this precedent could in practice give the big tech co's something like a soft-veto on any political candidate.
