There used to be a three-strikes rule (as @knapplc mentioned) but - as you say - I'm not sure that's really fair. Three strikes in a year isn't good. Three strikes in 10 years probably isn't that bad. So I really haven't seen a hard-and-fast three strikes rule applied since I've been involved. We try to look at the whole picture, including longevity.
We've had a similar discussion about whether the points should expire after so long. If they expired after, say, two years then a three strikes rule may be appropriate. Be I have always spoken in favor of keeping them permanent - so there is a record of history - but also taking into account that stuff from a long time ago probably doesn't have much bearing on any current punishment - unless it's something they've been specifically instructed to not do.
If I’m told not to call someone a moron in 2012 I might do it again because I’m hungry at the time of the post.
