Bulk Trade issue

I put 1 map for sale for 1 ex and got spammed for the sale, however, people can in expecting 60 plus maps, one even called me a MF when i only had one, on testing the search using my own map and searching for myself it seems when you put the bar up to 70 it still shows someone selling 1, ie me so the filter needs setting to account for how many people are selling. i dont need to abused for selling a single item of something that can be bulk sold. Maybe mark as bulk could be an option in game or the abiily to add a number for something you can sell in bulk but doesnt stack.
