Dead bodies in cities (horde) with weird names (Lordaeron)

So I was walking around Orgimmar, saw dead bodies laying around, ''diehorde'' and all that crap, don't really care that much, wonder how these bodies can keep laying there for literal days though, it's something I don't understand, do they just log off when they're dead and then never come back, and the body lays there for an eternitiy?

In Thunder Bluff, in the pool next to the mining things, there are several dead taurens's bodies drowning with weird names, offensive #%$@, can't say it before I get banned, just wondering how this is even possible, and how they do it. Maybe take a look into this though, cuz I believe some people won't like seeing those names on those dead taurens.

I'd say it's rare for someone to go and inspect the names of drowned taurens.

Basically yes, you die and never resurrect and your body stays there for a few days.
