nope. subed. but i asked the OF suport because if it was true, because that would mean i needed to get some money back. they told me. if you have renew on you get charged. they dont need to post just to log in, but the OF account will get deactivated after longer time of being offline with no posts. 3+ months or if they get reported.
Now if you're talking about a girl who still has an account and you're not subscribed to them and it wants to charge you. That would make sense. Because you're still trying to access the account. Maybe it also depends on the backend settings too. I have only ever purchased and never charged for anything.
