Auction House BOTS fix suggestion
Auction house bots took whole auction house in their hand.
I've been doing auction heavily for months (if not even a year) now and there are just few specific items that you are able to sell constantly without being undercut immediately by a bot. I find it very unhealthy for the game if level 2 and level 3 characters are undercutting you every 2 minutes 24/7 and never going offline for weeks, effectively making you lose gold or just not be able to earn gold. I have personally came across many bots and reporting them does only so much - they get banned (using vpn) - they make new account - do same thing on new level 3 character - repeat.
A way to fight it:
Simply put auction cap per level. If you are level 3 character there is absolutely no reason to put 600 auctions a day. Instead of everyone being able to post freely, if there was level restriction up untill higher levels you could fix botting problem.
How exactly would I make auction scaling per level? I would put that on each level you get to post 5 auctions per day untill level 40, then the restriction ends. Why level 40? Because any less level is just easy and fast to level up to. If you put level 20 as a cap, they can just level it fairly quickly and do the same for a week untill they get banned and repeat. Level 40 without heirlooms (Which you cant get unless you already have 80 char on account) takes few hours even so it would significantly decrease botting, if not even completely stop it.
Someone would say if it's level 40 cap then they can just make Death Knight - for that you need to have character over 55 first so they would have to level it up anyway.
There is no actual human player without malicious intent level 3 posting 500 auctions per day, only bots. And even if there is an actual human on character level 3 (I came across 2 actual humans out of 100 bots), you can just post auctions on your main character OR if you want character whose only purpose is for auction house posting, I don't see an issue investing hour or two leveling it up to 40 ONCE and have it just for auction since you will be able to keep that character and won't be getting banned if you are a human.
