I'm not expecting perfection, but there hasn't even been visible commitment to a strong moderation policy. ernst has as far as I can tell remained mostly silent on the matter, occasionally deflecting to "tools aren't ready yet", but also not really committing to what he wants to be done with the tools.
10A is a particularly prolific problematic user, and as a single user (unlike the flood of porn spam) it's a simple matter to ban him. It should not have been a hard decision to make by now.
Personally, a bit over a month ago, I defined banning 10A (as well as one other individual) as the canary that would let me consider recommending other people come here. I was willing to give it some time, but it hasn't happened yet. Whether this is an explicit policy of weak moderation, or simply an accidental one thanks to putting it at too low a priority, I don't know. But I don't particularly want to be on a site that I don't feel comfortable recommending other people use. So I'm taking my own (lack of) recommendation for now and going to take a long break from this site.
And my comment. In a private window I can see that he replied to my comment as well, despite the fact that I blocked him, so blocks are still not working properly apparently.
