Spamming with empty links

savecancel

I wantet to point to a tricky spam posibillity. If a spammer posts a regular question with an empty link inside,

 [](http://my-mega-spammy-site.bla)

then you cant see this unless you click on the edit-button. A search engine crawler can see it though

One solution would be a predefined minimum amount of characters in every link
