Re: /LFF ... *crickets*
The pug warden hate, even I'm guilty of it. If I'm on, say, my captain, and need a tank for a group, I'm very leery of inviting a warden I don't actually know. To be fair I'm pretty leery of inviting a guard I don't actually know either, but I'd rather take a subpar guard than a subpar warden. A subpar guard still has force taunts. A subpar warden is just useless.
Back before /glff broke on my account so I couldn't read it anymore, I used to tank pug runs and I would often get some skepticism regarding my ability to handle it before we actually went in. I never really blamed people for it either... as long as they actually gave me the chance to prove myself, I wasn't worried about my ability to do so. And if they didn't, not my problem. (Although I did call out one guy on glff who kept asking for "guard or champ" for HoC a while back and dared him to let me tank for him... and after that run I kept getting tells from him asking me to tank it for him again!)
I think the moral of the story is, just take the chances that you can to prove yourself... answer those "5/6 need tank" LFFs and if you show that you can do a good job, you'll get repeat invitations. If you're answering "5/6 any class" generally what people really want is a dps rather than a second tank, so of course you're likely to get passed over. Once you get a few successful runs under your belt, start getting to know people, then another lff you answer can end up with someone you grouped with before and they can say, oh yeah I know that guy, he can tank.
If all else fails, start groups yourself and show the people you invite that you can tank.
