>The domain is not blocked at the moment
Yes, that was unblocked yesterday morning via other ESET support's help. Thanks for the answer, anyway.
>Strange that there are "legit" domains with offensive 3-letter words in the name and show only a smile on the main page.
That website is DynDNS'ed one (my home computer), and it serves for several small projects within one domain name (in different folders). They are totally separated from each other, have different visitors etc. This is the reason I do not create the main page - there is nothing crosslinked among them all but the smile.
