"WndSks" isn't funny, clever or even the slightest bit ironic. It's just rude. Raymond is well correct to point this out. It's not unreasonable to expect a little common courtesy from those to whom you provide so much value. For Free.
Try this:
1. Go to McDonald's
2. Tell them the food they prepare sucks.
3. Order some food.
4. Enjoy the spit (or worse) that comes as a bonus condiment on your food.
