I received a message that I am "followed" on GeogebraTube.
Why am I followed? I never publish on GeogebraTube.
How to get rid of him? I never asked or permitted to be followed by people I don"t know.
A creepy feature of this forum!
The same question 
now you have a new creepy follower
Hope I am not creepy. Just followed you on Geogebra Materials page.
I have been learning of your works since 2008.
Followed your sites : http://www.vandeveen.nl/Wiskunde/Demo/Dissectie_Dudeney_auto.html (now not viewable in Chrome)
and your updated site at http://www.vandeveen.nl/index.html
Thank you for sharing your amazing visual teaching ideas and resources!
