I remember hearing that POE tracks when you trade on external sites like jsp or RMT; how do people usually conduct their trades here to not get banned by POE servers?

harder than before just not mentioning jsp doesnt cut it anymore, you need to check who you are trading with, profile, trading history, you name it

i dont think poe tracks your browser if thats what you meant

Ok I see; do they have people on jsp looking for users to ban or something?

There was a rumor going around years ago that they did. But they dont have to when people go into games in town full of people and go:

HUE ME LIKE FG HAS ITEM FOR GOLD GOOD I BUY YOU LIKE YES DO NOW.

And literally dont look at any hints people leave about trading because they will instantly cool down or ban for that.

google will return results from D2JSP if you type (SELLING 2 DIVINE SANCTUM) and filter by date, not rocket science but as long as names are kept private you should be ok unless your doing some really big trades from what i heard
