As far as I understand it now, if one of my friends (from a community server or otherwise) makes me an unlimited friend, I can see their files and any files i transfer with them as source or target even if I keep them as a limited friend?
I think this is sort of problematic, I don't want to know what files people I don't know have and I don't want to know what it is I am forwarding since that in a sense makes me liable for any questionable content.
My suggestion: Only allow friends to be non-limited if both parties uncheck the limited-box.
Is this something you would consider?
