I flagged the two accounts again and the JMod has manually moved both accounts to Lumbridge.
The JMod suggested that, if it happens again, you submit a contact via the Technical part of the website.

Malua, I'm having a similar problem except I am not a member, I never have been, and didn't really wanna be, I tried logging into a f2p world, and it keeps telling me I'm standing in a members only area... It's literally not possible since I am NOT a member and haven't ever been. Please, I just want to be able to play my account.
I suspect you have been hijacked and a membership added in order to move your account into the members area, probably to be used as a bot.
To get back into the game, you WILL have to chose a members world to log into then move yourself back to a F2p area.
I then recommend you review your security.
