I think the reasons for not being allowed to complain are pretty fair though, it’s not going to make any positive difference (and you’ll more likely end up Streisand Effecting yourself), and it’s uninteresting for everybody else.
I see it as not so much “take your lumps”, but more like “Meh, haters gonna hate - just ignore them.” Not a perfect solution, sure, but if you wanna participate on a anonymous/pseudonymous forum, that’s kinda inevitable. What’s the alternative?
