Advertising
noun
the act or practice of calling public attention to one's product, service, need, etc., especially by paid announcements in newspapers and magazines, over radio or television, on billboards, etc.
There is a number search box on leolist that is easily usable and only searches the number field. You could search any number at any time. Nobody was stopping you from doing that. The only thing that happened is some of our ads were displayed to you, which, is typically the goal of advertising, and of which, you don't need to click on.
Seriously, this is ridiculous. If you don't like those ads, don't click on them. Simple.
