How many times must this be said, Saying necropost alert doesn't help the problem. If you believe somebody is necro-posting then send them a private message about it; This lazy-ness of calling out necro-posting is in-itself, spamming and necroposting. And to give this a bit more of a personal touch to make it truly stick; Calling out necro-posting publicly is mere vanity, doing it merely to make yourself seem more impressive.
Here's a slighly modified bible quote that'll fit if you're one of those christian folks:
And when thou comments on necroposting, thou shalt not be as the hypocrites are: for they love to comment on necroposting standing in the big threads and in the profile posts, that they may be seen of men. Verily I say unto you, They have their reward.
But thou, when thou comments on necropsoting, enter into thy closet, and when thou hast shut thy door, send a private message to the person who necroposted which is in secret; and thy Father which seeth in secret shall reward thee openly.
