You do realize that even if you "safe" this, someone can easily DOS you using the right formulas?

In my opinion, the scope of the problem depends on your environment. Using such a thing on the public internet would be a bad idea.

If you have such a tool in your companies intranet (preferably only accessible via some form of authentification), the DOS problem is probably non-existent or at most a one-off thing (e.g. something that can be taken care of permanently by calling the human resources department).
