I am not sure what you mean by "listed"
It really doesn't matter, but I do have degrees from two universities and have taught for more than a few colleges/universities in three different states. I have been on FB for a few years, and I think I know it fairly well.

I think I am credible when I post IMO lol
I mostly refrain from posting when I doubt my own credibility...seriousy, I think I delete more than I post
I am not questioning your credibility. Just stating my own experience of NOT having a college/university email account... but yet... there they are on my FB page. Just perplexed is all. Maybe I get a pass since I'm so old. LOL.
