}      if requested ad size is bad:
}          return {skip, bad_size}
}      if the game has ads disabled:
}          return {skip, disabled}
}      if the game is filtering a domain:
}          return {skip, domain_filtered}
}      return choose_ad()

	try begin
		case requested_ad_size(Size) of
			bad ->
				throw(bad_size);
			_ ->
				ok
		end,
		case has_ads() of
			true ->
				throw(disabled);
			false ->
				ok
		end,
		case is_filtering() of
			true ->
				throw(domain_filtered);
			false ->
				ok
		end
	end of
		ok ->
