I coined the word ‘mathlusiverse’ which means ‘Universe is Illusion of Mathematics’ many years ago. I later purchased the domain ‘mathlusiverse dot com’. I value the creative word ‘mathlusiverse’ and respect visitors to my web site. The original web site contained high quality materials suitable for all audience. It also contained 100% free educational tutorials and products. All contents were professionally created by me.
Some scums purchased the domain as soon as it is expired and converted it to a porn site, with the evil intent to embarrass me into buying back the domain at high price. This is so sickening! I do not connive blackmail! I am sorry if you see any inappropriate contents in my old web site.
mathlusiverse dot com 網站已經運行多年了，內容全部健康，積極，高质量，有教育價值。亦包括免費教程和產品。多年来我自己付費購買和開發那個網站，創造和免费提供內容。內容均為 100% 免費！
有人渣看中那個網站的流量，一過期後立即購買並換為色情網站。人渣要我以高價將網址買回來。我不會縱容勒索！
如果大家無意中探訪舊網址，看到人渣放置的色情圖片，引起大家噁心，深感歉意！
