I have a question about competition on ppc

I have a website that is in a niche market. I have seen another website doing something somewhat close to what I am doing. I see their google adwords ads, and was just curious if I cliked on them hundreds of times what would that do? Would that be helping them with traffic, or hurting them for the click. I am not doing this, however I am about to start advertising with adwords and just don’t want this website to be able to do this to me! I want to see all of my options before I lose any money. Thank for all the help
