Your best bet here is, sadly, probably to switch to some other hosting for the files.
I would personally recommend
Github. While it's nominally made for techy types, they have great free file hosting for public projects, and there's a desktop client so you don't need to know the particulars of the backend software that they're using (git). Their project storage also lets you keep the full history of a text file and split/merge different versions based on what you're working on.
