The main threat for normal, well-behaved people is the growth of services that encourage us to put all our eggs in one basket, multiplying the routes by which you might attract the wrath of The TOS Overlords.

An example would be the number of people who don't want to issue perfectly valid chargebacks against Amazon because they'll lose access to digital purchases (kindle, audible, etc) in retaliation.

So more on-topic, it's conceivable that, for example, you have a dispute over a Google Play purchase, and in trying to exercise your consumer rights, you lose your access to your gmail account.

You don't need to be a troll to be violating a TOS, "if they're being punished they must have deserved it" is no more valid online than off.
