AH bots on Outland?

Hi,

I've been playing for 1-2 years on Outland, and always seen the same random named lvl1 chars putting insane amount of 20/20 stack of items on AH. They are not flippers, as they always sell it the cheapest, all kinds of stuff(the things resellers wont bother). The amount of item they put up there can not be farmed by 1 player, like they put up 4000 medium leathers.
I reported them a lot of times with screenshots, names, etc, nothing happened.

If these random named (like Cnmbb, Lzblm) lvl1 chars are not resellers of items farmed by Bots, what are they? A lot of these lvl1 chars exist since a year doing the same thing all day.

Thank you
