Degree Diploma mills good?? No!!

through search in the internet good information about the word degree / diploma mills through the "unrecognized universities/colleges/schools/​seminaries!!
Now too many books filled with "Dr." and it is not worth to buy and should check it out completely about the author's background "what kind of degree" and where the degree come from "what kind of school" That kind of action is not worth to trust that kind of author!! Because of the trust that people can depend on the right person to teach and it should be kept in highly recognized degree from the real recognized school! Right now too many "Dr" that is not good! i believe that the person should be more honest about their degrees so people can depend on the teachings! For me if a person has degree / diploma from the unrecognized school and I rather not to depend upon or learn from that person who cheat on a unrecognized degree from unrecognized school! No thanks period! thanks for watch my vlog ken
