heheh, don't know about torches but I got this strange thought that it's possible that caring members (including you) post and create the content value that draws possibly a large percentage of 'outside' bandwidth that the caring members then pay for, because they care.
so a solution might be attachment access restriction until a new username time expiry or small instant membership payment.
But thinking of solutions doesn't help unless there is a problem, that's why I asked.
It could be that the 'caring' members just continuously run up the bill because they are really addicts and refresh every 60 seconds. :P
