Unfortunately I can't access TD's link, problem with not connecting (been happening on a few sites the last two days)
>> Only two out of the nine actually said what these limits wereSo I am going to "assume" one of those two are Virgin Media!
Yes they do cap (throttle back) at certain times of the day and night if we/I abuse the UL or DL limit during those periods, but at least we know when they are.
Providing they don't change the times or limits and don't bother to update the site, then it's not quite as bad as I first thought it would be.
Although I have been informed that it works on a automatic blanket system once a person has been detected as going over the limit, which could well be "unfair" for a non P2P user who quite genuinely needs to transfer large files during these times.

Finally managed to access the original link.
Virgin Media certainly don't appear to have a monthly limit, although if they do then I have never hit it.
However, the following quote I feel is incorrect, as I have had long periods of either very low or no activity whatsoever when the Traffic Management system was first implemented and have still fallen foul of their traffic management for seemingly no reason whatsoever.
Do do not believe that this is only being monitored on heavy users only.
Virgin Media - unlimited but traffic of heavy users is shaped at busy times
