Kirstey,
Accidental control zone entries happen all the time (at least here in the US they do). I work at an airport with a Class C airspace, so for us it depends on the degree of the violation and whether or not it caused us problems (did we shut of departures or break out arrivals because you got in the way) whether or not we Hunt you down.
Most controllers would rather spend a few minutes on the phone talking to a pilot about the potential problems with violating a control zone than doing a bunch of paper work, I call this educate rather than violate, but sometimes we don't have a choice (depending on how bad you violated the airspace and the problems that you caused).
For example with a class C airspace it is possible for a pilot to cross off the end of my departure runway or arrival runway at 1400 msl and just a fraction over 5 miles and be legal, is it safe "NO" because you could become a hood ornament on another acft.
