Technically it's against the ToS (using 3rd pt softwares/tools), but it's impossible for SE to detect. And as long as you're still sitting in front of the screen, you'll be fine. This thing is pretty normal for MMOs these days, I would be more concern about this if it were nProtect, that thing scans your PC for running programs before launching the game.

But looking at how peaceful all the RMT bots & teleport hacks are around, there's really nothing to be afraid of... Although I don't think you should discuss this on the forum, lol.
