Considering how much meme RPers rely on backtagging nowadays, it'd probably make things really confusing if there was some kind of daily requirement. Also, not every person who signed up is going to be available/in the mood to RP every single day for most likely over a week, and it wouldn't really be fair to spring a requirement like that onto everyone at this point.

And while that mechanic would make the characters more desperate to kill and survive IC, it could easily lead to instances of muns godmodding in order to keep playing as long as possible, and that could make things super not-fun for a lot of people very quickly. ;u;
