Keep in mind that it is possible for the lender to boot you off the account at any time. Therefore, it is unwise to put anything you'd mind losing on a rented account unless you fully trust the owner.

Please note that you must provide video evidence in order to file a scam report against an account lender for booting you off an account you're renting. Extremely damning evidence (i.e., the lender admitting to booting you off) suffices, but in a vast majority of cases, a video will be necessary.

Facebook associating with RS Account Scam:

Remember to check your facebook/runescape account associations before and after EVERY transaction involving someone else having access to your account.

This method was recently highlighted in the suggestions forum and makes your accounts very liable to being raided, they dont even need your Runescape password to do it, just as long as they've used your account at least once to associate with it.

A way of preventing this is doing it yourself or making sure its not associated after EVERY transaction such as an upgrade or service performed on your RS account, or even bought accounts.

 

Sticky edited to reflect a new rule requiring video evidence for scam reports against lenders. Record yourselves on the accounts you rent!
