Bad codes for Kindle/etc posts.

I think I've figured out why I've been so bothered about the constant posts for things 'for sale'.

It's not actually that they're being posted for sale. It's that they aren't actually using the codes that are _supposed_ to be there on the front page. I've found myself, more than once, thinking that it's an update, and finding out it's another "HEY, DOPPLER" or "KINDLE BOOK". - but it says 'SOLO' or 'Day Of The Week' instead.

At the top of the page -

Codes: Solo=Standalone story, not series, verse, drabble or fanfic; Source codes: HB=Hatbox; DP=Doppler Press; KS=Kindle Store; AB=Amazon Book; LL=Lulu; SW=SmashWords; SD=Stardust; SS=StorySite; SP=Sapphire's Place; FM=FictionMania. Default is day of week.

So, is there a reason why nobody is using the DP, KS, AB, etc codes? Are they broken for the authors (or mods) posting up the notifications?
