80 posts in a week is quite a bit, unless you're one of a few Evangelists on the board.

If you're caught post padding, you may be sanctioned, and kept out for a longer period. If you did 80 posts in 5 years, and then another 100 in a week, that's certainly not a normal type of behavior.

For those wanting to do similar, just find a good way to contribute to the forums without going crazy.
