Purpose of `increment_blocks`.

There is no total_blocks property on this model, so are inheriting classes meant to implement it, or is this old code that can be removed?

It looks like it was never properly implemented (see https://github.com/django-oscar/django-oscar-accounts/commit/76d59317c82b5798844e51292bc9f07a1ee55665) and has always been broken. Looks like record_blocked_request isn't used anywhere either so the simplest path at this stage is just to remove this code.
