I'll be perfectly honest. I have had the oh-so-delightful experience of being attacked personally for my role as a moderator. It's stupid, and childish, and not what I expected from people on this site, but I tend to give people more credit than they deserve, it seems. Apparently, not only did these bullies never bother to actually read the Terms of Service and Content Guidelines that they agreed to when making their account, they find it unreasonable for us to expect them to actually comply with it.
Although we now use a separate moderator account for our work here, I don't think I'm alone in remaining reluctant to expose myself to the bullshit of retaliation reviews. While I'm intelligent enough not to take the content to heart, I'm also hampered in how I can respond because I am a mod for the site, and even in my "personal" role, what I do and say reflects on the site as a whole. I know that standing up to bullies works, but I can't do that, and silence only encourages that particular form of vermin, whereas I'd rather hold up a mirror and force them to confront their own blindingly evident inadequacies.
Even worse, they help to alienate readers and authors who would otherwise leave reviews that were meaningful and contained useful concrit. I enjoy being told what worked, but even more so, I want to know what doesn't work. I will never improve if I don't know where I'm lacking, and I'm not delusional enough to think I don't have vast room for improvement. I particularly resent losing the gorgeous and invaluable concrit from ShadowKnight, and the blunter but no less cherished concrit from wanderingaddict. They kept me going when I started writing here, and I've taken their advice to heart, to my great benefit.
The utter nadir, though, is seeing writers with talent and potential crushed by bullies who unleash the full fury of their minions on someone who dares to leave a less than fanpoodling review. It's not in my scope of authority, but I'd cheerfully ban those bullies without a moment's hesitation. I never permitted my children to throw tantrums in public and if certain users want to behave like children, I'm more than happy to administer swift parental response. Being an adult comprises more than just having reached a certain chronological benchmark.
