I'm still not clear on this either. Remembering the difference between down and up, I see no such thing as a per person download limit. As I said I allow 20 uploads per person but that message still appears for them. I allow max 3 simultaneous uploads, but more only causes Queuing. Is it when they are downloading more than their max downloads at one time, and I see that Limit message? On their end it would just Queue (yikes how do you spell that word).
And I still say I don't want anyone banned from my collection. That goes against the very point of collecting things that are great.
Oh and max 20 uploads per person - I hope that only applies per session, not lifetime.
