I find it hard to believe they would ban someone for "bad packets" alone... you had have been doing something... routers send "bad packets" all the fucking time, thats why there are designated bits in each packet that gets sent out to verify if it made it in one piece (good packet) or didn't (bad packet)....
If by "bad packet" you mean you reinterpreted what they said so that you can flame ppl on here then all the more power to you, but so far you're the only person to every use the "bad packet" excuse... finding it hard to believe...
I 3-box and they all share the same router and cable modem and i've yet to be banned for "bad packets"
