Toolserver users need to renew their accounts every so often[1] (Three
monthly is combing to mind, but someone else would need to confirm
(and they are given warnings I believe)), and if a user fails to do
that it is automatically locked, It's unfair to all TS users if user
accounts are allowed to exist forever using the shared resources of a
free service.
I think you should reconsider the tone you used in this email as it
came over as being extremely harsh and consider apologising.
Perhaps you could try to contact Phe and ask that they login to their
account and run the renewal process?
