How do I make sure someone stays permanently offline on Yahoo chat?

[K D]

For years I was able to put people permanently offline before deleting them from my friend's list and i never had to worry about them again. On the new program this feature is a nightmare. People I haven't talked to in years are commenting on my profile pic or sending messages. Apparently all of them see me back online even though I didn't change their status. When I went into the status feature, I realized that even after I went through every name in my address book and switched them to permanently offline, the very next time I signed in it switched them all back to available. If I delete them from my contact list do they still have access to my account as I haven't completely deleted them from that. It seems that I can do all I want but until they delete me from their llists they have all the control. I feel like I have no privacy what-so-ever once I accept them as a friend. Ironically, people still in my friend's list remain offline until I manually change it, but no one I removed from it.
Also, I access yahoo chat through my bb, my computer at work as the web-based version, and at home on the downloaded version. Is it possible that they are in some conflict with each other? Thank for your help.
Aaron, if you don't know what you're talking about, grow up and stop wasting people's time. The juvenile comments get really boring.
