Instead of saying things, go do things.
You are like one of those protesters, holding a sign to make yourself feel good(you did something, right?), instead of actually doing something about it.
And there are multiple things you can do, you can sift it with addons, you can collect evidence and report them, you can bid on their 1 coppers some 70-80% market value to grind them into losing gold. You can even make a proper and argumented suggestion to change the sorting into "by buyout per item" across all pages, that would eliminate 1 copper dudes instantly and make everything more competitive with less room for bots.
ps
You say you can see bot just by opening AH. What? Tell us this magical secret knowledge, so GMs can go and ban them. I'm sure you wouldn't go and accuse people without any proof, just because you don't understand whats possible to be done on AH by 1 legit player.
