anyone else been finding people you've blocked on your list or unblocked suddenly and fairly recently without your personal doing?

nope. maybe you should ask the help section on there?

I've had messages I've deleted come back. Like old old conversations with Adrianna from 2005.

But not something like that to my knowledge.

hmmm... def. will have to look into this then. thanks for the suggestion caitlyn. =) I can't understand why old messages would come back o.o

No kidding. I was pretty mad that day. I hope you get it sorted out.
