*knock on wood* It's nearly impossible to get banned for RWT if you're safe. As the users said above, try to trade in increments. A lot of my friends and I trade wealth between each other on the daily, lending items and whatnot. What I typically do is filter the gold through my alt accounts and have my friends transfer it to my main. There's virtually no way Jagex would detect it in that case unless you are a repeat offender.
