#' Read account rules
#'
#' Returns a tibble of all the rules for an account. Rules are
#' applied to mentions as they are received by BrandsEye.
#'
#' Rules can be read from various different kinds of object. An [account()]
#' object is the most basic, although rules can also be read from a list of
#' account objects (in which case the returned tibble will include an account code column),
#' or from a tibble containing an account code column, such as that returned
#' by [account_list()].
#'
#' @param x               An object to read logs from.
#' @param .show.progress  A logical indicating whether to show a progress bar or not.
#'                        By default, this only shows a progress bar in interactive environments.
#'                        Also, progress bars will only be shown if 5 or more accounts are
#'                        being examined.
