Something strange is going on at the marketplace

At the moment it is impossible to buy logbooks via marketplace, since ~yesterday everytime I tried to buy logbooks for exalteds, absolut every seller I want to join gives me the message "This sellers account has been banned"(why are they even shown if they are banned?) and if someone lists a logbook freshly it gets instantly bought and put back in for orb of annulement instead of exalts.

It seems someone is already botting logbooks and is trying to manipulate the marketplace, its really annoying because I like to level with logbooks.

I had logbooks up for weeks with no one buying them. 5c each. Maybe more than they're actually worth, but barely enough to make me use a portal scroll to sell them.

Probably bots that go as far as they can and get banned.

Are logbooks the new bot baseline farm?
