We do still get DMCA notices, and we tend to get at least one every month. But at some point, Lumen removed the usual submission form that we were using to report these to their database, without warning (or at least we never received any). It actually took me some time to figure this out. I was going to submit a batch of them one day and it took me near half an hour to track down an old link to the form that, sure enough, just said they no longer accept online submissions. So, we stopped submitting the reports.
There is a back-door process for these that larger companies with fancy forms and databases use to report them, but we don't have any of that tooling that would let us send reports to them automatically. So it looks like we're just out of luck for reporting to them unless they decide to re-enable that form or we put a bunch of work into creating those systems, which is unlikely to happen given how few of these we even get (again, we're talking about 1-2 on average per month, because we've worked with some of the people that send them regularly to combine them into a sort of monthly report).
That said, I did recently bring this up internally when I noticed the submission form was gone and couldn't submit further notices, and the idea of creating our own transparency report was even floated. We don't have any hard timeline or idea of what we're going to do, but some expected upcoming changes to how we process DMCA notices may make it a lot easier to generate that transparency report automatically without much, if any, effort on our part - so it may very well become a thing. Fortunately the way we have been processing them will make it quite easy to update and track these reports retroactively for a fair bit of time too.
As of right now, this irks us because the rug was kind of pulled out under out feet. We want to do something to continue reporting this kind of information. We just don't know exactly what that way is going to be or look like at this time.
