how could you have an issue with this? They can't do anything to prevent it once the page has loaded, you should never use a bot to click on search results, if thats what you're doing as they catch on pretty fast but just harvesting... as long as you are setting appropriate delays between pressing "next" it should be ok but you need to let it wait a while in between, I'm not sure on the amount of time but think of how fast a person would go through a page of results so it has to be reasonable.
