One of my first internet experience was on a forum for a kid tv channel. There was a point system where posting a message would give you a point and certain amount of points would grant you ranks. I discovered that sending private messages also counted and clicking space repeatedly when submitting a message would multiply the message and the points. I am sorry to whoever received thousands of mps every single day back then but I had a lot of fun increasing that rank.

That may also explain why I still like incremental games nowadays
