As someone who witnessed what Krushramrada posted before it was deleted, I figured I'd offer my one cent (because two is too costly). I think that regardless of how good or funny posts are (it was), spamming is kind of annoying, as it requires scrolling through a whole bunch of posts, which is especially a pain if these posts have signatures. So I can understand how this isn't acceptable in the TalkBack, as it looks pretty messy on the article page.
I think it would be fine in the Funhouse, but I agree with it not being allowed somewhere like TalkBack.
