Adding on to the last post, this site is helpful for looking for a suitable server to transfer/start again on :
WoW Guild Rankings :: WoWProgress - World of Warcraft Rankings and History
I used it to choose a new euro server and at pretty much all hours of the day, even when i cant sleep and have wandered on at 3am I have seen ads in /2 looking for people for naxx pugs and loads of guilds recruiting for Ulduar etc. The caveat to that is that almost every pug ad expects you to link your epic and naxx achievements etc but if you are feeling brave you can use the fake achievements mod to at least get your foot in the door. Not sure how you are supposed to hide the messages when you start spamming them upon killing the first boss etc
