Vexatious or repeated requests. 14. - (1) Section 1(1) does not oblige a public authority to comply with a request for information if the request is vexatious.
(2) Where a public authority has previously complied with a request for information which was made by any person, it is not obliged to comply with a subsequent identical or substantially similar request from that person unless a reasonable interval has elapsed between compliance with the previous request and the making of the current request.
-----
The thing here is the request has to be
identical or substantially similar the emphsis on substantially. Im sure you could re-word your FOI so that its not substantially similar but only slightly similar.
Slightly does not count as grounds for refusal under S.14.
As for your complaint, Id send an email to her ladyship telling her that using S.14 is in effect "denying you free speech".
Point out The Human Rights Act 1998, Article's 9 and 10 spring to mind. (

Plus you could also play the race/religion/etc card and say that they are denying you the information you requested because you live abroad (it says FL in your bio)
