typo-squatting 

say you want to search on Google.com for teletubbies.com, britneyspears.com, metallica.com, linkinpark.com, (or any other website with correct spelling names,) and you misspell the proper name such as mettallica.com, linkinnparc.com, (because you don't know the correct spelling) you are directed to porn sites or spyware.
and most of these typos are done by children who are under the age of 18...see also cyber-squatters
