To be fair, this is precisely going against the spirit of the request.the genie could just interpret that as being their spirit, not yours, and just screw you even harder.
Also, the spirit of the request means the intention behind it, and precisely the intention of the one formulating the request.
But even if we assume "the spirit of the request as understood by the genie", the genie is intelligent enough to perfectly understand that spirit, and to pervert it would be precisely to go against it.

Anyhow, only the powerful requests can be thwarted, or the standard ones also?
For example, a request for a +1 inherent bonus or for a 20000 gp value gem can be distorted?
