Twitter also has privacy settings that can "lock" the profile to the outside world, pretty much the same as Facebook.It's much more complicated you don't have to just search through a load of profiles, the bot needs to be able to skip past pages/profiles that don't allow public viewing and things.
Why does facebook send less traffic to outside websites than Twitter?
I think Facebook is designed to keep the community contained within Facebook and to send as little traffic outside the site itself as it can.
