As a former Comcast employee, I can tell you that half the crap that comes up in the news about them is pure garbage. And to be fair, cable companies aren't the only ones booting people for ridiculous usage - there are cell phone companies who boot people who have like 6 users constantly on one phone day and night too. My recommendation is not to download so much crap that you can't even watch it all, and when you're done downloading, don't seed a bunch back for too long. Comcast has to pay to maintain the lines and when you sit there downloading day and night and eating up all the bandwidth, it makes hard times for people like me, who want to play online games without lagging out a bunch.
Just something to think about. And yes, you can sign up for a business account and technically they don't verify the social you give them if you claim it's a sole proprietorship. It's $60 a month for comcast workplace, so if the extra money is worth it to you, go for it.
And DSL is even worse than cable, so don't bother IMHO.
That's my .02.
That's called bait and switch. Comcast can cap my bandwidth (and I don't think that uncapping your modem is legal or fair to the cable company), after all, they sell you the service based primarily on speed, but when they advertise "unlimited" uploading or downloading volume, and they really have a secret volume cap. Even if they no longer advertise "unlimited" they still refuse to say what their cap is, which is still unfair to their customers who have no idea when they are suddenly in trouble. Basically, they don't want you to use the service they sell you, which by rights they cannot do. Instead, they should just tell you what the cap on your volume is.
As an analogy, if this was a meal, the restaurant owner can't just sit there and watch me eat half the meal, and take away the second half when I reach for it because they also sold that same meal to somebody else. But that's what Comcast is doing. It's not my fault they don't have enough to go around, but they can't sell me a meal and tell me I can't eat the whole thing. And I'm not going to feel bad about using what I pay for.
And, no offense to you, gemineye, but I don't hear about Verizon or Qwest doing this sort of thing nearly as often as I hear about Comcast doing it. The only thing from either of them that I can remember is that Verizon once got caught censoring somebody, but they at least backed off and apologized for it when they were found out. Comcast isn't backing off.
