Don't waste a penny on them
H.E. Master Maitreya Samyaksambuddha (https://buddhistnations-gov.net/2018/08/01/president/)
Let me break down the name for you
H.E. - His Excellency - This shows Mana or pride. No matter what Buddhist text you follow Abhidharma or Theravada, it will teach that arrogance and pride are illnesses of the mind
Maitreya - Is the reincarnation of Buddha in the current times.
Samyaksambuddha - Is someone who has attained nirvana (there is a lot more to this)
So yes the claim of being the promised Buddha goes a long way in explaining the trait of a teacher which lacks humility
Now, there is nothing wrong on calling oneself H.E. Buddha himself and presiding over a university with rate card without classrooms or any qualifications or lineage whatsoever or anything remotely close to zen or Buddhist values. Some people may choose to do business in the name of Buddha and that’s a moral wrongdoing.
But let's put attention to other things that you asked for.
International Buddhist Ethics Committee & Buddhist Tribunal on Human Rights
These 2 organizations are affiliated to the same university via United Buddhist Nations Organization (buddhistnations-gov.net) registered in 2017
Starting with the domain you can say this site has been created to falsely promote the university as a GOVERNMENT unit.
They conduct trials on individuals for reasons ranging from war crimes to un Buddha-like behavior.
buddhistcourt-gov.net - A domain registered in 2017
This tribunal - uses a proton mail id and claims to be a legal body that has rights internationally to prosecute anyone it deems fit from United Nations to World Leaders to a common man
They send out notices in legal language accusing vaguely of things like waging war, fraud, and 100s of such things with a threat to malign and defame people. Which Buddhist in his right mind would do this
Just look at some of the cases online and you would see so many cases posted on educational portals and academia.
If they get offended by you, they will put a case on you :) I am doing this at the cost of being at the receiving end of one such notice
Above all, the cases are judged by Mr. H.E. himself - Now if that's not a fair trial, then what is?
So to answer your questions - As someone who has devoted her life to meditation, I can tell you don’t waste your time on this. There is no university, there are no classes and there is a massive scam of scaring people with -gov in the urls
Put that money to buy a big tub of ice cream and stare at it instead :D
