-I bought around 3b one time (i'd say 5 months ago) and got a 14 day ban a few weeks after buying... after that 14 days, i logged in on that account and they didn't take the 3b away... was surprised... i wonder if it being my 1st offense (ban/mute meter) in 14 years made a difference...
-Just recently i bought around 1.2b on a diff account and got a 14 day ban as well... logged in and they took that 1.2b away...
both accounts are maxed... i'd say the chance of Jagex taking the gold is high. from my experience and research. they really are cracking down RWT's like crazy now
Usually RWT bans are permanent but if you have an old account and you don't RWT too often then it might be a minor ban. In that case they usually should leave the gold in your account as it means they are not 100% sure about the ban.
