Using an incremental number (linkId) as the shortened URL lets any user "guess" all shortened URLs anyone has ever added, thus leaks all real URLs of your smart contract.

Also: please use tripple backticks (before the first and after the last code line) instead of single backticks (around each code line) for better visualisation of your code.
