You criticized what you identified as an "advice" for not providing work to your scope (which you clarified as "make a better thing than Anubis"), why should I suddenly have to meet your scope of "work" to be a valid criticism of your advice this time? Showing a negative result is also work.
If your moral framework is supporting a nominally good "solution" with no evidence (where if your evidence that your assertion the solution is "proven"?) is "a good outcome", pointing out the solution is flawed, with evidence, is somehow not, then you'd be right. I personally do not share your nominal goodness compass, however.
Codeberg and sourcehut[1] have both blogged about Anubis decreasing loads on their servers at the beginning of the year when this saga has started. Since then, one, or both have moved to different solutions, but that was not due to ineffectiveness but rather to requiring JavaScript.

If you're operating your reasoning in a moral framework where helping the bad agents is a good outcome, then you'd be right. I personally do not, however.
