DT itself is "moderated" by the community

We like to think it is, but it's not too good. And I'm not talking about Timelord2067 here. There's quite a known trust cycle from where every time some
people users get into DT.
It may be an unpopular opinion but I fear that if your red tag will be removed you may start spamming the forum just to meet your posting quota.
That may be, but negative feedback shouldn't be used against spam.
You are right. And I already said that imho the negative feedback was too harsh. But since we were analyzing the situation from all the angles, I thought it's a detail that very much deserves to be mentioned.
