Misinformation on surname
This site is filled with misinformation such as on the surname Ami. It is not of Bangladesh, Asian or African origin, it's of Italian/ Swiss and French origin. These people are spreading misinformation that migrants bearing this name in European countries are Asian and African. This is absolutely not true. They even cite Caucasian people with the name on the page, yet write fake statistics and misinformation on its origin and race. Anyone using this name of Asian origin has shortened down their long name or is using an alias name, it's not their real name. The name has a strong history of being Italian, Swiss and French.
Most Bangladesh people do not have a surname, they usually go by first and middle names, therefore Ami is unlikely to be classed as a Bangladesh surname. In Bangladesh, Indonesia, Nigeria and other Asian and African countries, they do not permit the disclosure of any electoral roll records or exam result lists of names, this information is kept confidential. The site has fake sources on this surname.
It appears to be that these sites use bots to create the statistics, scrape data and guess data using bots which is often inaccurate. They are in general writing lies on this surname and many other surnames.
