I really hope that your enjoyment of the forum has not been dented by your experiences in this thread.
As you may have gathered from my criticism of the Japanese nationality laws, I believe that if you have ancestors from a particular country, you should be allowed citizenship of that country. So, I am very disappointed that Finland has changed the rules. But, I'm sure they had a good (probably economic) reason to do so.
And thank you for pointing out about the strictness of the Estonian laws. The member that suggested that possibility later admitted that they were guessing in their suggestions!
By the way, if anybody is interested, I started another thread today which is directly derived from this thread. It is about the possible consequences of representing a different country, and can be found at:
Hope you enjoy reading my thoughts
