The fun thing with HughesNet is, multiple people often get assigned the same IP at the same time. I had the opportunity to file a ban appeal on 4chan once, but when I went to do so, I found someone else had already done so. I went ahead and added my thing nonetheless, confirming the other person's story; when I checked back later, I found three other people had added to the appeal.
I have no idea if anything was ever done, because my IP changed again at some point. Was still crazy to see HughesNet's system hurting multiple users at once that way, though.
(This should never be an issue on my current Internet connection, because we pay extra for an ISP-side static IP. This is so that DCC send and receive in IRC work, and so that I have open NAT for Xbox LIVE.)
