IM, or Instant Messengers, are used by pretty much anyone who touches a computer. There are many types of instant messengers and IM clients and there are even some types that are solely meant for combining all messenger types into one client. Below you can find a list and description of these pedophile ridden applications.
Types of Client
Most people use MSN messenger for personal contacts. It is general more time consuming to setup fake accounts and it is a muhc bulkier and bugridden interface. You cannot run the newest version of MSN without a computer that is minimum 1 GHz with 512MB RAM or you will face massive lag in all applications. Most people use MSN to get on cam with others.
Yahoo! Instant Messenger, or YIM, or Y! for even shorter, is an IM that pretty much no one uses. It is a backup messenger that pedophiles fall back on if they can't get anything on AIM or MSN. Getting whores to show their tits on Y! is a pasttime for many pedophiles, with groups made just for sharing Y! video or image captures.
Pidgin used to be known as Gaim, when it was crappy, but since it changed names it became the best client out there for combining your IM user lists.
Pidgin can work with all of these protocols listed: AIM, ICQ, Jabber/XMPP, MSN Messenger, Yahoo!, Bonjour, Gadu-Gadu, IRC, Novell GroupWise Messenger, QQ, Lotus Sametime, SILC, SIMPLE, MySpaceIM, and Zephyr. It runs on Windows, Linux, and other UNIX operating systems as well as having a version for OS X called Adium.
It is an extremely convenient IM for pedophiles due to the ability to have all of his contacts in one client.
Skype is a voice chat service that was purchased by Microsoft.
