You shouldn't have many problems just browsing the classified adds. Just be careful clicking or following any links and be careful emailing somebody. A-lot of times they will provide a false email address so they can obtain a list of valid email addresses and either SPAM them or sale the list to a spammer. For dang sure don't email somebody that has a foreign email address they'll be something like this
Someone@domain.cn or
Someone@domain.de.
I hate Hackers!!!!
