I use /trade and /general when looking for HC Sen pugs as its quicker and easier but other times im am not logged into them.
Unfortunately some people have got wise to this and spam LookingForGroup and LocalDefense with crap as well so I had left them all on my main toon (the broken one). I'll stay connected to LocalDefense and just ignore ppl now as I have cleared my ignore list.
Thanks for the info and the help.
