Over on TBB in the general forum an anonymous poster is claiming to be on 50Mbps (although he quoted the price incorrectly) and received a letter complaining about his usage. He also says when phoning he was told that 150GB was the level at which VM may take action.
It doesn't look to be a total fabrication as he put up a copy of the letter..

This is contrary to all I've read about VM and 150GB limit for a 50Mbps user seems to me to be stingy given the price. O2 LLU on ADSL can cost as little as £7.50 and they have never to my knowledge invoked their FUP.
If this is true then what is the point of introducing 100Mbps - the only reason that makes any sense taking 50Mbps is for bulk downloading.
