If you are short on time for this issue, you other option might be to
prevent them access to the system (TSO/ISPF) and then have someone submit
the JCL for them.
Or you will, as others suggested, need to use an exit.
If you have time and money, you could look at a product like EASYEXIT by DTS

No, I do not think you can recapture the data easily

Then you would need to close and reopen SYSPRINT.

Paging like this also occurred when running a paging OS under
(z/)VM(/VSE). If you made the MVS space too large, VM would be paging
out the least recently used frame to make room for MVS to page in an
even older frame to use for the next frame.

That's typical. If each compression reduced the size of the file, every
file could be compressed with enough iterations to a
8 bits per byte, all ones.
To do it right, the first should have 57885161%8 ones, but that probably doesn't
change the compression much. But okay:
