Content Exchange Reset?

Was there a reset to the Content Exchange for Pollers for NPM? I have found links to older ones (including ones I made previously) but they are all empty. The integrated content exchange in the application doesn't have any historical ones. Is there a way to get any of the old content exchange pollers back? I've tried searching for answers but everything is many many years old.

Having to re-learn the poller version of RegEx is infuriating as there are minimal resources and examples to use and a large majority of standard RegEx tokens do not work.
