Necrobumping isn't -that- strictly frowned upon. What people generally have a problem with is if someone makes a bunch of necrobumps at once and floods the first few pages of comments.
Necrobumping with insightful commentary and relevant witty musings is greatly welcomed; it brings attention to old works and allows potential newbies to see classic content they may not have seen before. Necrobumping with one-phrase non-sensical / 4chan-ish interjections, or commenting just for the sake of commenting, will attract mods to your path very, very quickly.
@zidana and Fly I see... So much for me yelling at another guy bumping up a pic the other day. But since that pic was a pseudo nightmare-fuel in disguise, I guess it is somewhat justified. Ugh, my spine is getting chilled again thinking about that pic.
Anyway, can anyone tell me where did that Reimu go?
