How to fix dead thread necromancy problems - skull icon / warning

[ShadowOfHarbringer]

I was thinking about how to curb the problem of thread necromancy, and came with following idea.

1. Show a skull icon like this (but smaller): on topic list next to threads that are not touched for 3/X months or more.
2. When replying to an old thread, show a big font red warning in a box like " Warning: The thread you are posting in is long dead"

What do you think ?

UPDATE:
3. When reading an old thread, show a big font red warning in a box like "Warning: The thread you are reading is long dead"

Perhaps bigger version of the icon could be added to warnings as well, so they are more noticeable.

I honestly don't view "thread necromancy" as a problem. As long as you bring it back with an on-topic post, of course.

A warning already comes up.  It reads

Try posting to this old thread of Bruce's if you want to see what I mean.

that warns the necrophiliac, but not the poor people who accidentally read 45 pages of old thread before realising it's from another era.

Yep, that could also produce a warning.

Maybe the font is too small, and there is no actual box, so people don't see it ?

For some reason I have the urge to wait 8 months and then post in this thread...
