I find this amusing.  The Puritans in society try to crack down on a victimless crime and the end result is they end up increasing the activity the very activity the were trying to stop.  From our neighbors to the north:

TORONTO -- A 2005 Supreme Court decision that cleared the way for swingers clubs appears to be bringing out Canada's more, well, adventurous side.

Those who prefer life closer to the edge of the conjugal bed say the high court's re-interpretation last December of the definition of indecency has fuelled a growing interest in private clubs that feature group sex, partner swapping, voyeurism and exhibitionism.

"I think there's a great opportunity to provide a safe environment where couples can really enhance their sex life," said Linda Fox, who operates Club Eden in Vancouver.

The same thing happens when there is talk of banning certain types of firearms.  The sales of those models and accessories dramatically increase.
