The dislike of the alleged influence of Slottsberg became more intense during Charles' reign as regent during the minority of his nephew king Gustav IV Adolf of Sweden in 1792–96. It is not known if she ever met the de facto regent Gustaf Adolf Reuterholm or had any real influence, but she was often mentioned in the political debate. When silk and coffee was (temporarily) banned in an extremely disliked sumptuary law by the regency government, the public opinion pointed to the disregard for this law among the upper classes and "In Stockholm it was loudly said, that as long as the mamsell's Slottsberg and Löf (the mistresses of the duke) wore silk and all kinds of finery, such things should not be banned."
