If your specific and narrowly scoped instructions cause the agent, acting on your behalf, to click that link that clearly isn't going to help it--a link that is only being clicked by the scrapers because the scrapers are blindly downloading everything they can find without having any real goal--then, frankly, you might as well be blocked also, as your narrowly scoped instructions must literally have been something like "scrape this website without paying any attention to what you are doing", as an actual agent--just like an actual human--wouldn't find our click that link (and that this is true has nothing at all to do with robots.txt).
