Recently, when I surfed the web, I stumbled onto this and had a deja vu. Despite I see that site for the first time, the answer there was indeed written by me. It's original can still be found here. While looking at that site further I found that it also contains a lot of other copypasta from MSE. It left me wondering, what purpose do such sites with copypasta serve. Everything that can be found there can be found on the original MSE with less effort, thus making such sites as the aforementioned one somewhat redundant. However, their mere existence indicates, that there is some demand for them. What purpose do such sites serve?
