I'd be inclined to agree here.  I note you (John) are running WP 2.7.1
on furrycritters.co.uk, so the CMS itself may not be responsible, but
perhaps one of the WP plugins installed, or more likely PHPBB, which is
a very popular attack vector, due to the myriad of holes in the various
versions of the code.

It is possible to enable SFTP access while restricting shell access.
Note that some large vendors, e.g. Dreamhost, do allow SSH access to
allow easy use of services such as cron jobs.

If they're banned from accessing your systems, how do they upload their
sites? :)  In all seriousness, how does restricting access to servers
stop problems with "Secure Code"?  If I can only upload files via FTP, I
can still upload some insecure code.  It's perfectly possible to enable
shell access for web hosting customers (I know, because I've done it) to
give them the maximum possible flexibility to build and manage sites,
while ensuring all the sites play nice with each other and the servers
that host them≈.

It's not always within a hosting provider's duty of care to QA customer
code, although I do believe it's in the same sphere for a provider to
use systems that mitigate against the effects of unfortunate code mistakes.
