It's true that it's possible 4chan will get blacklisted, however they've got a few things going for them. The majority of the boards (note: not the traffic, but the boards) are SFW. There are lots of moderators. THAT BOARD only has scuzzy, and most of the time it's because I'm looking through my als archive and see some CP and tell scuzzy about it in his IRC channel. Although there is a /torrents/ board there, and it's almost all pr0n, but the thing they have going for them is they don't run the tracker.
Either way, it doesn't make much sense to link to image boards since the content in the link gets pushed off the face of the universe in a matter of days (4chan) or a few weeks (THAT BOARD).
