Surely any mod, otherwise you'd be suggesting that whatever mod altered the rating (at OP's request) was in cahoots with the escort?
Had a mod suggested the rating should be changed or even worse gone ahead and done it, as I seem to recall a forum helper did in the past, then there would be an issue. That does not appear to be the case here. Even if she does know a mod, they are unlikely to publicly support her on this site, even if they privately had some sympathy for her.
