Look, if you're going to buy accounts, record them botting for several minutes, and if you're going to buy gold, record the whole RWT experience at least the first 3 times.
What this does is simple, but highly effective. If the account is recovered, you upload the videos and send them to jagex, post them on the appropriate reddit (oldschool/rs3/etc) and several other venues. This ensures that the scammer loses the account they use to scam people with. Please protect yourself and use this simple tip to eliminate the trash that steals from you.
