Is Miraslav Marek's, Genealogy.EU considered a reliable source?

Question

Hi,

I am sure I have come across Miraslav Marek's genealogy.EU as being a reliable source site on Wikitree but now can not locate where I found this. web address as follows: http://genealogy.euweb.cz/index.html

Am I correct or misguided?

thanks

On the single page I pulled up, Grimaldi, there was not a single primary or secondary source listed for the information presented. So, in that case, this is not a reliable source.
