The service I'm using hasn't given me any problems within my year and a half of using it, but a lot of other people have gotten booted for bandwidth consumption.
I'm paying about $140 a year for my hosting (1 GB Storage and...well we won't get into Bandwidth limits, but 'Unlimited' is what's advertised). Haven't had a server crash or been capped yet for bandwidth, so I can't complain.
Of course I'm not going to name the service, because that just causes a mad rush of people to it.
