BT has warned 400 of its AnyTime customers that they might be using the Net access service too much.
The email issued yesterday said: "After reviewing our records recently, we have reason to believe that your account has been active for online sessions during extended periods of time when it has not been used."
It suggests that this might be due to punters "leaving the Internet connection maintained whilst not using the service" or because "accounts have been compromised and are being used by people other than yourself".
Either way, BT hopes that this softly-softly approach will give a gentle nudge to people over their online activities.
Although BTinternet Anytime is a 24/7 unmetered Net access product, it is not designed to be "always on". BT has made it clear that extended use of BTinternet Anytime breached its terms and conditions.
However, while the telco stopped short of issuing any threats to boot people off unless they curb their usage, a spokesman for the company said that this remained the "ultimate sanction". ®
