"When you delete IP content, it is deleted in a manner similar to emptying the recycle bin on a computer. However, you understand that removed content may persist in backup copies for a reasonable period of time (but will not be available to others)."
This sounds like they properly delete it but only so long as you haven't given another user a copy of it (such as sending a message perhaps).
Also while the US has essentially no privacy protections whatsoever, I don't think a "deleted=true" would fly under EU regulations.
