I have seen this website before, and don't worry, it is not serious at all. It is just all in parody. I personally don't think this is one of the best comic things related to LOTR, but it is okay. So just read it, enjoy it, and have an enjoyable time
And besides just look at the name of the website: Pointlesswasteoftime.com
Do you really think a serious website would actually have a name like that?
