No, but some people will exasperate. Some might even lie. The Internet part is only for finding people who you'd like to meet and weeding out the rest. Don't go a long time before you meet them in person.
nothing online is fraudulent
its just another avenue of dating, there are frauds in every situation
my cousin goes on dating sites that dont charge and finds one night stands
Not always... but the people on them are often quite sketchy... :-(
An interesting way to test these sites is to create both a male and female profile and see if they charge the dudes more. lol
