Land investing education programs not recommended

[Blake Ryan]

Hey, first post.  I have seen a lot of posts here about what land investing programs are the best.
I want to go at it a different way.  What programs or teachers are the ones you would not recommend?

I was looking at Kendall and Only Land Fans.  He is in my area but the more I looked the more skeptical I became.
A bunch of his videos are just him working out with words about investing written across them.
His business name is very unprofessional.  My girlfriend finds it offensive and I guess others do too.
He says to do one thing in one video and then the next week he says something else. 
He also says to do a lot of things that others are not saying to do.  This could mean that he is a trend setter but he does not have the deals to back that up and has not been investing long.  
A lot of things raising a lot of questions.

Do any of you agree or disagree with my view?  
I am looking at other options.  Are there any others that you would say to make sure to avoid?
