Well the past weeks I've been in a complete fire festival haze disregarding most of anything else including about 500g in returned auctions that I probably should've checked before the timer on them expired.
Still compared to the 10+ levels I managed to scrounge up through honoring/desecrating fires I'd say 500g is a paltry sum.
Suffice to say I spent a lot of time travelling and when each of your characters passes through Org or whatever other capitol city you may prefer you can't help but notice the immense amount of corpses littering the ground spelling out some obscure gold-selling site (and the fire festival has tought me that even the alliance capitols are covered in corpsevertisement).
I am not against creative advertisement... after all if I had a script that'd drop 50 corpses from the sky spelling out something you'd probably see my name written across the barrens more than a few times (or maybe someone else's if it attracts the banhammer).
The problem is that
a) it never gets cleaned up: You have to see the damned graffiti each and every day and no GM really seems to give a hoot that it's there
b) you can't make use of the advertisement because the second you actually go to the advertised site and buy their goods you're breaking the TOS and may find yourself getting banned at some time in the future, even if it is months or years further down the line.
So basically we're looking at little more than what is often referred to as 'jailbait'. Something that entices you to break the law and will get you banned but is still there and awfully tempting (for some).
I am always a little surprised that blizzard doesn't at least try and do something about it like automatically delete corpses in town after 2 mins forcing people to rez at a healer. In the end it kind of feels like the advertisement is being condoned making people think they might as well buy some gold only to be punished by blizzard who is basically exposing us to the advertisement in the first place.
Thus I would like to propose that players are given the option to remove those kinds of corpses themselves, especially considering the fact that no one else does it.
Give me a torch to set them on fire, allow me to incinerate them in a flurry of fireworks or at the very least give me a shovel that'll make it possible to burry corpses. You could even have some fun with it and throw together an achievement for it that leads to a nifty title like 'the undertaker' after you burried your 1000th corpse.
Make it only useable in town and it doesn't strike me as something would be able to abuse too easily and I would happily spend 5 minutes of my time deleting the corpsevertisement even if it is only to see them fall from the sky again a few minutes later (make the gold sellers work for it at least).
I hereby volunteer for the position of undertaker. I'll be needing a shovel, some tomb-stones, a wicked evil accent, some dark clothes and maybe a hurse of some sort...
