It looks like the best way to get the Guardian to consider a complaint about this is if someone "personally and directly affected" puts in the complaint:
The readers’ editor office was created to resolve substantial complaints and queries from individuals who feel we’ve breached the Guardian’s editorial standards. As such, the readers’ editor’s time, effort and resources will be focused on such complaints, and she reserves the right not to consider complaints:
- From anyone not personally and directly affected by the matter which forms the subject of the complaint.
- That are trivial, hypothetical or otherwise vexatious or insignificant.
- That are without justification (such as an attempt to argue a point of view or to lobby).
- About advertising (unless in exceptional circumstances).
- About Guardian reader offers.
- That are legal complaints.

iii) A fair opportunity to reply to significant inaccuracies should be given, when reasonably called for.
iv) While free to editorialise and campaign, a publication must distinguish clearly between comment, conjecture and fact.
v) A publication must report fairly and accurately the outcome of an action for defamation to which it has been a party, unless an agreed settlement states otherwise, or an agreed statement is published.
