The forum is a great place to share information and advices, but it is a shame that it's so infested by trolls providing cool stories and advices even on the serious sections (outside /k).
It's dangerous and toxic for the community to continue housing the dupes who only want to stir things up like racial/gender/religion/any sort of discrimination.
With the tag, people can better decide whether to feed the troll for fun like in /k, or take their stories/advices with a pinch of salt when it's a serious topic.
Dupe tag can be assigned in two ways:
1. By mods: you cannot untag yourself if so. Can be disputed but case by case basis.
2. By yourself: un/set yourself under user settings, useful in times you need help but do not want to be associated with your main account.
For now I assume mods detect dupes manually, and that's fine. Community can use the report button as usual to report bad behaviours, then mods can act upon dupes who appear too often on the baddies list.
"show possible/confirmed dupe of X"?
Honestly I don't want this to be a blanket implementation. Some people dupe without malicious intent and that's fine for me. I just don't like when some take it too far to bring their toxicity to the forum and there is no repercussions to their "real self".
Dupe tag, please
