[Can I trade with my sister without getting banned?]

Thanks for the replies! I'll look into sending slots as gifts which seems like the safest way to go.

[Can I trade with my sister without getting banned?]

I recently got my sister to start playing Warframe and she's loving it! However she recently got into a problem where she is running out of inventory slots for weapons and warframes. She is really bad at trading plat and doesn't want to spend money on the game (yet). I have a few thousand plat saved up and was wondering if I can trade with my sister without getting banned. We live in the same house and I can see how the anti cheat system could think that I'm using a second account to boost myself.
