Why do I get spammed for Tabula Rasa?

I've sold 2 Tabulas so far in Standard Expedition League, both times I got giga spammed as soon as I listed the item for trade.

Both times I checked poe trade and listed my item for the same price as the other lowest prices (1st time 8c 2nd time 10c). Are these listing fake price fixed listings? Why do I get spammed when I list this item?

Probably bots. Because you listed it low they are programmed to try and buy it up. I would go to poe.ninja and list your item for it says.
