To be fair and avoid confusion, surely the posts from someone who has left, should be removed

Yes, she asked to leave. And frankly its a shame as she is a very knowlegable lady but she had "issues" with the site.

JG posted a thread called 'stirring' having a go at Dogwebbers - JG was told this was not acceptable and any similar instances would end in a ban.. she asked to leave so her account was deleted. We don't have room for people who 'have a go' at our members.

The reason peoples posts are left up if their account is deleted is because the posts may be part of a thread and if deleted, may disrupt the 'flow' of the thread.

It would be more confusion if bits of the 'conversation' were missing.
