不知廉耻

'Shameless' is a direct English counterpart for this Chinese web name. People with such moniker seem bold without any scruple. On the surface, they look indifferent or defiant toward what society traditionally sees as shameful or unacceptable conduct. This kind of person tends to go against conventional norms or customs freely. It may refer to those whose confidence makes them unbothered by social judgment, yet sometimes could have more negative implications
