They no longer recruit. There were a few still active on the testlive server & testlive forums. I remember back in 2010, when I first got into Tortage city I got a PM from one asking if I needed any help and to enjoy my stay in Hyboria. Never saw them again in-game after that.
Edit:
http://cs.ageofconan.com/Public/ The website is still up. Looks like the Secret World had their own variant "The Pest Control", which is probably inactive as well.
2nd Edit: On an unrelated note,
http://guilds.ageofconan.com/ is still up too. Any day now it will make it out of beta lol.
