Providers on mfc?

I know this may have been asked numerous time before but I'm going to refresh the question. Do any providers use mfc? I figure it may be a good way for hobbyists to "get to know" providers and maybe use it as an alternative screening. I really RARELY hobby as time is a factor but I do frequent mfc because the interaction is exciting. However, I don't want to ask a cam girl if she's in the hobby so I figured I'd reverse the process.
