In that context it's completely fair to say "leaving doesn't absolve you of past transgressions".
Edit. If Imgur made any revenue from UK users then it becomes impossible to claim plausible deniability on any definition of "providing a service". If the UK can do something about this is a different matter. They could make CEOs/board personally or even criminally liable for the company's failure to pay a fine but probably won't.
