Per https://w.wiki/DeQh, we are well within our estimations about the day amount of requests still reaching this service. It's in the order of ~1900 and we had estimated ~2k.

requestctl rules set, the API now responds 403. Let's keep it like this for a week or so to see if anyone complains and then proceed with killing it.

This is still true. Excluding an attack we received on May 13, we are still on the order of ~2k to 2.5k requests per day. I would have love to see it becoming less, but that's apparently not gonna happen. Not with the amount of out of date wikipedia apps out there.
