::::::::::::::: OMG.  
 :::::::::::::::: 1. There is a whole network of old Slavonic fortified settlements in Slovakia and Moravia. There is not any serious academic discussion if they existed in the 9th-10th century and if they were inhabited by Slavs. Boroska, discussions like "they may or may have not been in use in the 9th and 10th centuries" belong to the scholarly discussions from 18th and maybe 19th century. Nowadays, it is proven, largely documented fact, completely independent on one or two sites.  
 :::::::::::::::: 2. Fakirbakir's theories that the (ex-)president of the archeological institute Alexander Ruttkay (by the way honorary member of the Hungarian Academy of Sciences) cannot distinguish between old Hungarian and old Slavonic archeological findings is ehm... no comment. 
 :::::::::::::::: 3. Naivety how do you believe that Slovak Academy of Sciences or the Archeological Institute somehow manipulates research or employs idiots who take ceramics from 12th century and than conclude that the location was inhabited by Slavs in the 9th century... no comment. Do you really believe it? I don't know where did you get this information.
