No matter how exaggerated the terms can be... if you agree to them, then you must follow them or face consequences.
Not true. All Terms must remain within set bounds of ethic and moral values, and workable for the consumer. It has occurred numerous times in the past that Terms were altered or negated altogether because they were deemed unreasonable in whatever way.

Banning or suspending paid accounts without prior warning or proof would easily fall under this category.
