Unless the author is insanely rich, they probably don't want to spend increasingly large amounts on hosting unless they have a way to make money back (even if it's just to break even).

I am not rich and I don't need to be to keep this service up and running at least for the near future.

To keep this up and running for 2-3 years, you probably do need to be rich, or to find a way to monetize.

It's possible when it gets to be a drain, even charging pennies for the service could drive off the bad actors making it unsustainable though.

For the foreseeable future and unless there is massive abuse, which I am trying to contain, it will remain free.
