Have done similar projects and can confirm. It’s not mentally sustainable.
It’s worth noting that it’s not exactly the uBlock devs who are updating the filter lists. The people who make the filter lists are pretty separate. Then lots of adblock extensions use those same lists.
Ah that makes sense then for the update list setting they give you. Either way I hope you have less stressful projects now!
The filter list people do generally accept donations btw. If you go through the uBlock Origin list configuration, you can find links to the homepages about some of the lists. If they accept donations, I’m sure there’ll be a prominent link.
I imagine this is pretty thankless work, so if adblock has been valuable to you, you may wish to research donating.
Disclaimer that I am not socially or financially associated with any mainstream internet ad blockers or filter lists.
