Shorte.st is a European-based website where people can earn money on shortened links, by using advertisements.
Like adF.ly, the website pays the user every time they shorten links to websites via advertisements. The user can only get paid if they have an account, has shortened a link and does not have an ad blocker.
While the website itself is not malicious, some of the ads that are displayed on the website once the user enters the shortened link can be fraudulent or pornographic. Some websites may also redirect the user to one of its shortened links. The website is less dangerous for those who have an ad blocker.
