Losing 3 months once would make them sit up and take notice. Alongside a fine you'd get a notice to improve, telling you what deficiencies you're being fined for and that you need to resolve them. Failure to resolve them results in... Another fine of similar magnitude. And another. And so on until you get your house in order.
Doing nothing is not an option. I suspect the one they'd take would be to do the absolute bare minimum and obey the letter of any notice rather than the spirit of it. Hence the current privacy theatre Google, Facebook, MS and others take you through occasionally where they get you to review their confusingly worded options.
