Do people actually sell their characters on warmane?

I have a few 80s that are pretty geared that I want to sell for coins via Warmane but seems the market is pretty saturated. I see you have to spend 5 coins per listing for what seems to be a small percentage of a successful sell. Anyone had luck with this? I never play the characters I want to sale but seems like id just be wasting coins at this point. Outside of maybe rare items or mounts; any tips? Not sure if its against ToS to post about this here but figured Id ask.

the "fee" is taken on successful sale.

So you sell for 30 coins -> you will get only 25 if someone buy the character

It is ok to ask questions about it, but not to announce/promote your sellings.

Also, all sales must be made through the Warmane official system.

99% of characters are not worth to buy, so market is not that big.
Make your character worthwhile, professions, flying, maybe some worthwhile gear pieces, etc
