well first of all, i dont know that anyone here got banned for using jsp
i mean yeah theres one guy who posts twice a year how he got banned, but that became a meme by now and no one even bothers to check if it actually happened or not
personally, when i trade, i use an alternate poe account, but without a vpn thats not much protection
just dont do two things: first, NEVER, never ever mention jsp ingame or you are fucked, when you trade you dont say "hi, mercyt@jsp here", you say "sup brother, u still need that amulet vs 20 exalts?". then ofc he puts 20ex in the trade window and you put some shit amulet, while sending him fgs for the exalts
and second, avoid trading with specific items. you risk being reported because items are easy to track, and you will get underpriced into oblivion anyways
